A woman with a tote bag raises a hand to ask if she can join three friends sharing coffee and a board game at a park picnic table

You are scrolling on a Saturday morning and see it: a friend's story. A group of people you know, laughing over brunch, tagged at a place ten minutes from your apartment. Nobody told you about it. Your chest does a small, familiar drop.

So what do you do? If you are like most people, you do nothing. You like the story, maybe send a heart emoji, and spend the rest of the morning composing a theory about why you were not invited.

Here is the twist. According to new research, there is a good chance you were not left out on purpose. And there is an even better chance that if you had typed "can I come?", your friend would have said yes, and barely thought twice about it.

This is a story about a tiny sentence that most of us are far too nervous to say, and why saying it might be one of the highest-return moves in adult friendship.

The research: people hesitate to ask, and hosts mind less than we think

In 2025, a team led by Julian Givi, a marketing professor at West Virginia University, published a set of eight experiments in Personality and Social Psychology Bulletin on something they call self-invitation hesitation. The idea is simple. Plenty of people want to join a friend's casual plans. Plenty of friends would be fine with it. And yet the people who want in often never ask.

The researchers compared the two sides of the table. The would-be joiners (the ones sitting at home, wishing they were included) consistently believed that asking would be a bother. The people who actually had the plans were far more relaxed about it than the joiners expected. Most people, it turns out, would rather be asked than have a friend quietly feel left out.

The findings come with a sensible boundary. They apply to everyday plans with people you already know, such as a movie, lunch, or a walk, not to weddings or baby showers, and not to people you have only just met. That is exactly the zone where most adult friendships live or die: the ordinary, repeatable stuff.

Why we hold back

The researchers point to a few mental habits that keep us quiet:

That first one deserves a second look. A lot of what we read as a snub is really a lack of attention. Your friends are busy, distracted, and mostly preoccupied with their own lives. They did not exclude you. They just did not remember you were available.

The flip side: saying no is easier than you think too

If asking feels scary, so does being asked. The same lead researcher has a separate set of studies, published in the Journal of Personality and Social Psychology in 2023, about declining invitations. Across five experiments with more than 2,000 participants, people who imagined turning down an invite expected their friend to be angrier and more disappointed than the people who had actually been turned down turned out to be.

In a pilot, 77% of respondents admitted they had accepted an invitation they did not want, purely out of worry about how a "no" would land.

Put the two findings together and a pattern shows up. We are all quietly terrified of each other's reactions, and we are mostly wrong. We avoid asking because we fear annoying people. We avoid declining because we fear hurting people. The result is a social world with far fewer plans, fewer invitations, and less spontaneity than any of us would actually prefer.

One caution from the researchers is worth keeping: saying no now and then is fine, but declining everything can wear on a friendship. If you want the full picture on that, we wrote about it in what the research says about canceling on a friend. The healthy middle is a relationship where yes, no, and "can I tag along?" are all comfortable things to say.

Reaching out is a surprise gift, not a burden

There is a third piece of the puzzle. A series of studies by Peggy Liu and colleagues at the University of Pittsburgh, involving more than 5,900 participants and published in 2022, found that people who reach out to others consistently underestimate how much the other person will appreciate it. A short note, a check-in, a small gift: the person on the receiving end valued it more than the sender guessed.

The effect was strongest when the message was a surprise, and when the two people were not especially close. In other words, the "weak tie" you are most nervous about contacting is often the person who would appreciate it most.

Taken together, these three lines of research tell a consistent story:

  1. Reaching out is appreciated more than you expect.
  2. Asking to join is welcomed more than you expect.
  3. Saying no is forgiven more easily than you expect.

The fear in each case is bigger than the thing it is guarding against. Social life, it seems, runs on a shared underestimate of how much other people like us and want us around.

Why this matters more as an adult

When you were 19, nobody had to ask to join anything. The plans were simply there: the dorm hallway, the cafeteria table, the group chat that was always loud. Proximity did the inviting for you.

Adult life removes all of that. We covered the structural reasons in our piece on the friendship cliff, and the lack of shared spaces in the third place crisis. The short version is that friendships now rarely happen by accident. They happen because someone says a sentence out loud.

That makes the hesitation to ask costly in a way it was not at 19. Each unasked "can I come?" is a small missed chance for a memory, a deeper bond, or a new person who turns into a close friend. Over a year, dozens of those moments evaporate, and we end up wondering why our calendars feel empty when everyone we know seems to be doing things.

It also explains a quieter version of friendship decline. In quiet quitting friendships, the slow fade rarely comes from a fight. It comes from two people, each assuming the other is too busy, each waiting for the other to make a move. Both are wishing for contact. Neither goes first.

How to ask to join without it being weird

Knowing the research is the easy part. The sentence itself still feels exposed. A few ways to make it lighter:

1. Make it easy to say no

The most effective asks come with an exit. "Totally fine if it's a close-friends thing, but I'd love to tag along if there's room" lets the other person respond honestly. Ironically, giving a graceful out makes a yes more likely and more genuine.

2. Keep it casual and specific

"Can I come?" beats "we should hang out sometime" every time. Vague hopes ask the other person to do the planning. A specific ask ("Mind if I join the Sunday walk?") gives them something easy to answer. If you want practice with low-stakes scenarios, start with activities that are naturally open: a pickup game, a coffee run, a walk with a dog.

3. Ask during the conversation, not after the photo

The best time to say "I'd love to come" is when someone mentions their plan out loud. If a friend says "we're hitting the climbing gym Thursday," that is your opening. Waiting until the plan is a screenshot makes it feel like a confrontation. Asking in the moment feels like enthusiasm.

4. Bring something small

Offering to grab the coffees, pick up a game, or drive makes you an easy addition rather than a logistical question mark. It also quietly signals that you are the kind of person who makes the plan better.

5. Flip it: be the one who invites

The researchers' advice to plan-holders is just as useful. When you mention your own plans, consider the friend who will never invite themselves, and invite them. The people most in need of an invite are often the ones least likely to ask for one. If you read our earlier post on why we stopped hosting friends, this is the same muscle: lower the bar, widen the circle, and let people in a little more often.

What if you do not have a plan to join yet?

The "can I come too?" advice has one obvious catch. It assumes you already have friends who are making plans. A lot of people, especially after a move, a breakup, or a job change, do not have that circle yet. There is no brunch story to feel left out of, only a quiet weekend and the question of where everyone went.

That is where the research is most encouraging and also where good design can help. The core insight is that people are more open than we assume. The missing piece is a low-risk way to find the plans in the first place, and a way to ask that does not feel like walking up to a stranger's table.

Let's was built around exactly that gap. Someone posts what they want to do (a round of golf, a coffee, pickleball, a movie tonight), and people nearby ask to join. The host decides who gets in. So the awkward "can I come?" moment is not something you have to improvise. It is the whole point of the app. Asking to join is expected, welcomed, and takes one tap. And because it matches you on the activity rather than on faces, you are showing up for something you actually want to do, which makes the first conversation much easier.

A few details matter for feeling safe doing this with people you have not met. Hosts are ID verified, and locations stay approximate until the host approves you. If you would rather keep things to people you already know, there is also a private mode for your own friends, with subgroups and direct invites, so you can be the person who finally says "who's in?" to the group chat.

If you are curious what is happening near you, you can browse events in your city or download the app and see what people nearby are planning. Run clubs, for example, work so well for new friendships because the "ask to join" step is built in, as we explained in why run clubs became America's easiest way to make friends. Let's aims to give that same open-door feeling to everything else.

Why small asks compound

There is one more reason to build the habit. In our look at fringeships and weak ties, we wrote about how casual, low-stakes connections carry real weight in wellbeing. Asking to join a plan is how many of those weak ties get started and strengthened. One Saturday walk becomes a standing Saturday walk. A friend of a friend becomes your friend.

And the stakes are bigger than they look. The U.S. Surgeon General's advisory on loneliness and isolation described social connection as a core determinant of health, and the people who feel most disconnected are often not short on kind people. They are short on small moments of contact that turn kind people into friends.

Each "can I come too?" is one of those moments. It costs you about five seconds of nerves. The research says the likely response is a shrug, a smile, and "of course."

Try this week

You do not need to overhaul your social life. Just run a small experiment:

The gap between wanting to be included and actually being included is often just one sentence wide. It turns out the people around you have been hoping you would say it. Say it this week, whether it is to a friend, a coworker, or someone nearby on Let's who is already planning something good.
