There is a version of you that lives in your best friend’s head, and you have never seen it.

They’ve described you to strangers, defended you in conversations you didn’t know were happening, kept a whole file on you: the year you fell apart, the thing you’re weirdly good at, the sentence you said in 2017 that they still quote at parties.

You have never once asked them what’s in it.

That’s the strange part of a best friendship. The questions to ask your best friend are the ones that never actually get asked, because you already know their coffee order and their mother’s maiden name and exactly how they sound when they’re lying about being fine. Not being close enough was never the problem. Being too close is.

Asking would mean admitting there’s something left to find out. There is. Below are 151 of them, sorted by what each one actually opens up.

Why Best Friend Questions Are Different From Friend Questions

Most lists of friendship questions are really lists of getting-to-know-you questions. What’s your favourite film. Where would you travel. Pizza or tacos. Fine questions, all of them, for someone you met last month.

They are useless on a best friend. You already know the answers, and worse, they already know that you know, which turns the whole exercise into a bit.

A best friend question has to do something different. It has to trade on the history rather than ignore it. The right question uses the eleven years as raw material: what they remember that you don’t, how their read on you has shifted, what they’ve been carrying that never found a natural moment to come out.

The research backs up why this pays. Jeffrey Hall’s study for the Journal of Social and Personal Relationships tried to put a number on friendship and found it takes somewhere around 200 hours together to move from friend to best friend. But the more interesting finding was buried in the method: hours alone didn’t predict closeness. What predicted it were what Hall called striving episodes, meaning catching up properly, joking, actually talking. Sitting in the same room watching something did close to nothing.

So the 200 hours you’ve already banked aren’t the point. What you did with them is.

The other reason to bother is unglamorous and well documented. The Harvard Study of Adult Development has followed the same families for over eighty years now, and its headline finding has stayed embarrassingly consistent across every decade: the quality of your close relationships predicts your health and happiness better than money, fame, or career. Not the number of people who’d come to your birthday. The quality of the few.

How to Ask Without Making It a Whole Thing

The main risk here isn’t awkwardness. It’s ceremony. If you announce that you’d like to ask some Meaningful Questions now, your best friend will make a joke about it, and they’ll be right to.

So don’t announce it. Drop one question into an ordinary conversation and let it sit there like it wasn’t planned. Driving works. Walking works. The last hour of a long night works best of all.

Answer it yourself first, or at least be ready to. A question you’re not willing to answer isn’t a question, it’s a test.

And one is plenty. You are not getting through this list. You’re finding the one that’s been waiting.

Questions Only Someone Who Was There Can Answer

Start here. These require the history, which means nobody else on earth could answer them, and there’s something quietly moving about asking a question that only one person qualifies for.

What’s your clearest memory of me from before we were properly friends?
What did you actually think of me when we first met?
What’s a moment from our friendship I’ve probably forgotten that you haven’t?
When did you decide I was a keeper?
What’s the worst you’ve ever seen me?
What’s the best you’ve ever seen me, and did I notice at the time?
Which version of me did you like least?
What’s something I did years ago that you still think about?
What’s a night out we had that you’d relive exactly as it happened?
Was there ever a point you thought we were going to drift?
What’s the biggest way I’ve changed since you met me?
What’s stayed exactly the same?
What did you know about my last relationship that you didn’t say?
What’s a phase of mine you were quietly waiting out?
If you had to pick one day of our friendship to keep, which one?

Watch what happens with the forgotten-moment question. Nine times out of ten it isn’t the dramatic night either of you would have predicted. It’s a Tuesday.

Questions About the Version of You They’re Carrying

Everyone wants to know how they’re seen and almost nobody asks, because asking sounds like fishing. It isn’t fishing if you genuinely want the unflattering half too.

How do you describe me to people who’ve never met me?
What do you think I’m better at than I think I am?
What do I overestimate myself on?
What’s something about me that other people misread?
What do you think I’m afraid of?
What’s my most annoying habit, honestly?
What would you warn someone about before they got close to me?
What do you think I’d be doing if I’d made one different decision?
When do you think I’m happiest?
What’s the thing I say all the time that I don’t realise I say?
Do I seem like I’m doing well right now?
What’s a compliment about me you’ve given someone else but never me?
Where do you think I’m settling?
What do you wish I’d stop apologising for?
If I asked for one piece of advice about my life and you had to give it, what would it be?

That last one is worth handling with care. It gives your friend permission to say the thing they’ve been sitting on for eighteen months, so only ask it if you want it.

Questions You Never Asked Because You Assumed You Knew

The blind spot of any long friendship. You built a model of this person years ago and have been running on it ever since, quietly not noticing the updates.

What do you actually believe about what happens when we die?
What’s something you’ve changed your mind about that I’d be surprised by?
What are you most proud of that has nothing to do with work?
What’s your relationship with your family really like these days?
What do you worry about at 3am?
What’s something you want that you’ve never said out loud?
Do you actually like your job or have you just stopped mentioning it?
What’s the thing you’d want said about you at the end?
What do you do when you’re alone that you’d never tell anyone?
What’s a part of your childhood I know nothing about?
Who do you miss?
What’s something you’re embarrassed to still care about?
Is there a version of your life you gave up on?
What do you need more of right now?
What’s the question you wish people asked you instead of the one they always ask?

Questions About the Friendship Itself

Romance gets rituals for this. Anniversaries, the state-of-things chat, the awkward conversation about where this is going. Friendship gets nothing, so the maintenance never happens, so it happens here instead.

What do you get from this friendship that you don’t get anywhere else?
What do you think I get from it?
What’s something you need from me that you’ve never asked for?
Am I a good friend to you, actually?
Where have I let you down?
What’s the unspoken rule of our friendship?
What’s a thing we do that would look insane to an outsider?
When was the last time you felt genuinely seen by me?
What would make us closer than we are now?
Do you think we’d be friends if we met today?
What’s the longest we’ve gone without talking, and did you notice?
What do you think keeps this working?
Is there anything you’ve been meaning to tell me?
What would you want me to do if you disappeared on everyone for a month?
Where do you think we’ll be in ten years?
What’s the thing you’d say about me in a speech?

“Am I a good friend to you, actually?” is the one people flinch at. It’s also the only question on this page that can change your behaviour by Thursday.

Questions for the Years You Missed

Best friendships almost never run uninterrupted. Someone moves, someone gets a demanding job, someone disappears into a relationship for two years. These are for the gap.

What did I miss that mattered?
What were you dealing with that you never mentioned?
Who became important to you while I wasn’t paying attention?
What did you learn about yourself in that stretch?
Was there a time you wanted to call me and didn’t?
What’s the hardest thing you’ve handled without telling me?
What changed about what you want out of life?
Is there anything you’re glad I wasn’t around for?
What do you know now that you’d have wanted to know then?
Who were you closest to when we weren’t talking much?
What did you think I was doing that whole time?
Did anything about me disappoint you in those years?
What’s the thing you most wanted to tell me and never got round to?
How do you want to do the next stretch differently?
What would it take for us to actually see each other more?

Questions That Are Just Fun, Because You’ve Earned It

Depth is not a personality. A best friendship is also the only relationship where you can be genuinely, unproductively stupid, and losing that is a worse fate than never going deep.

Which of my exes would you least want to be stuck in a lift with?
What would my villain origin story be?
If you had to bet on how I die, what’s the cause?
Which of us would survive longer in a horror film, and be honest?
What’s my most embarrassing recurring behaviour?
What would you title the documentary about my twenties?
Which of my opinions do you think is genuinely indefensible?
What’s a lie I’ve told that you let slide?
If we committed a crime together, what’s the crime and who confesses first?
What’s the worst outfit I’ve ever worn in your presence?
Which of my friends would you keep if you had to keep one?
What’s my ranking among your friends, no diplomacy?
What would you spend my money on?
What’s a talent I have that’s completely useless?
If you had to describe me in three words to someone I’ll never meet, what are they?
What’s the pettiest thing you’ve ever held against me?

Questions About Who They’re Becoming

The mistake in a long friendship is treating the other person as finished. They’re not. Neither are you, and the update is the interesting part.

What are you working on that has nothing to do with your job?
Who are you trying to become?
What are you better at now than you were at twenty-five?
What’s something you’ve stopped wanting?
What would you do if you knew nobody would judge you for it?
What’s the risk you keep not taking?
What are you outgrowing right now?
What do you want your forties to look like?
What’s a habit you’ve built that you’re quietly proud of?
Who’s influencing you most right now?
What are you curious about for no practical reason?
What would you want to be doing if money were handled?
What’s the next hard thing?
What do you want that you feel silly admitting?
What would the version of you from ten years ago make of you now?

Questions for a Friendship That’s Gone Quiet

Not every best friendship is currently thriving. Some are in the phase where you both mean to text and neither does, and the longer it goes the higher the bar for breaking it feels. These lower the bar.

What’s been taking up all your space lately?
How are you, and I mean properly?
What’s changed for you this year?
Is anything wrong that I don’t know about?
Have I done something?
What would you want from me right now if you could ask for anything?
Do you feel like we’ve drifted, or is it just life?
What’s the good news you haven’t told anyone yet?
What’s the bad news you haven’t told anyone yet?
What do you need that you’re not getting from anyone?
What’s the thing you’d want me to remember about this period later?
Is there anything you want to say that you’ve been putting off?
What would make this easier for you?
Can I do anything, and I mean a specific thing, not a vague offer?
When can I see you?

Note the shape of the second-to-last one. “Let me know if you need anything” puts the work on the person already struggling. Naming one concrete thing you’ll do doesn’t.

Questions for 2am

There’s a register that only exists late, when everyone else has gone home and the lights are low and neither of you has quite decided to go to bed. These belong to that hour and tend to sound strange in daylight.

What’s the loneliest you’ve ever been?
What do you think you’re here for?
What’s the thing you’d undo?
Have you ever been genuinely happy for a sustained stretch?
What are you pretending is fine?
What’s the closest you’ve come to giving up on something that mattered?
Do you feel known by anyone?
What’s the thought you keep having that you don’t say?
What scared you most about growing up?
Who do you forgive and who don’t you?
What would you tell yourself at nineteen?
What’s the love you didn’t get?
Is there a conversation you’ll never get to have?
What do you want to be true about your life that isn’t yet?
What are you hoping for?

Questions You’ve Been Saving

The last ones. These are less questions than admissions in question form, which is why they’ve stayed unasked for years.

Do you know how much you matter to me?
Have I ever told you what you got me through?
What’s the thing I’ve never thanked you for?
Do you know I’d come, whatever it was?
Is there anything you’ve forgiven me for that I never apologised for?
What do you want me to say at your wedding?
What would you want me to tell your kids about you?
Who would you want me to call first?
What do you want me to remember about you?
Is there anything you’d want to have said if we ran out of time?
What’s the best thing that’s come out of knowing me?
What’s the best thing that’s come out of me knowing you?
Are we good?
Same time next year?

A Few Things to Keep in Mind

Don’t run the list. Fourteen questions in a row is an interview, and your best friend will start giving you interview answers, which are the worst kind. One question, properly followed, is the whole evening.

Follow up on the answer rather than moving to the next item. “What was that like?” and “how long has that been going on?” do more work than any question on this page. The first answer is almost never the real one.

Accept a no without negotiating. “I don’t want to get into that tonight” is a complete sentence, and letting it stand without a follow-up is exactly what makes you the person they come to next time.

And don’t be surprised if the depth doesn’t cost you the banter. Greater Good Berkeley’s summary of the research on healthy social connection notes that people with roughly three to five genuinely close friendships report the lowest levels of loneliness and anxiety. Three to five. Not fifty. The whole game is depth in a small number of relationships, and you’re already holding one of them.

One Last Thing

There’s a reason these questions have gone unasked for years, and it isn’t that you didn’t think of them. It’s that every one of them contains a small confession. To ask your best friend how they’d describe you is to admit you care what they think. To ask whether you’ve been a good friend is to admit you’re not certain.

Most people never make that admission, on the theory that the other person already knows. They usually don’t. They’re standing on the same side of the same gap, waiting for someone to go first, assuming it would be strange to start.

So start. Pick one question from this page, ask it tonight in the middle of something ordinary, and answer it yourself before they can deflect. The person who knows you better than anyone has an answer ready for a question nobody has ever bothered to ask them.
