Adult Friendship Requires Administration

Nobody warns you that friendship stops happening on its own. In school, a shared hallway did the work. Adults get no hallway. Friends sit across a city, and each of you is busy.

That's not only nostalgia. A large meta-analysis of 277 studies found that friendship networks tend to shrink through adulthood. Life events such as entering work and becoming a parent were associated with similar changes. Family network size stayed relatively stable [2].

When I think about the friends I've lost touch with, there wasn't one reason it happened.

One of my first best friends was a guy from school. We were inseparable. After we graduated we went our separate ways, and even though we lived close enough, our busy schedules let the friendship fade. It's a standard story. When you're younger it's easy to make new friends, which is what I did, and I'm sure he did too. Now we keep in touch on Facebook on birthdays, and that's about it.

As an adult I had a trio, and people called it a bromance. Then one of us moved to France and another moved to upstate New York. Distance was the issue, and we faded. Messages got less frequent. We meet maybe once a year now. We're friends, just not close friends, and we have to work to catch up because our lives look so different.

Now, I don't have children, and many of my friends, like the ones I mentioned above, do. In a weird way, kids can get in the way of friendship. When I lived in New Jersey, I had several friends from India. After about 15 years, they moved to Northern New Jersey while I moved into the city. Their lives revolved around children, soccer practice, and the like. I preferred the hustle and bustle.

Nobody broke up with anybody. We just stopped.

Family has ways of pulling people back together. Friends usually have to make that happen themselves. One 18-month study followed 25 students. Their friendships were more sensitive than family ties to drops in contact and shared activity [3]. Friendship has very few built-in obligations, and that may be part of the problem. Two people can care about each other for years without either one being required to make the next call.

So the friendships that survive adulthood are often the ones somebody keeps putting on the calendar.

The 200-Hour Problem

Jeffrey Hall, a communication researcher at the University of Kansas, tried to estimate how much time people spend together as a friendship deepens. His study, first published online in 2018, put it at roughly 40 to 60 hours for a casual friend. A friend took 80 to 100 hours, and a close friend more than 200 [1] [5].

Leisure time mattered more than sharing a workplace or classroom. In the first study, time together at work or school was associated with less closeness. Hanging out, watching movies and playing games were associated with more. Catching up and joking around predicted growing closeness in the second part of the study [1].

Treat the numbers as estimates, not a formula. One sample was 355 adults who had recently moved. The other was 112 first-year university students followed over nine weeks. Both were about new friends [1].

Two hundred hours is five full work weeks. If you're working or already have an active social life, that person has to stay on your activity radar, so to speak.

Why Scheduling Feels Cold

Putting a friend into a calendar can feel like admitting the friendship is weak. I read it the other way. A plan on the calendar means the friendship made it through a busy week.

Spontaneity works better when people live nearby and have free evenings. Once everyone is busy and scattered across a city, it gets harder. If you wait for the mood to strike, the mood mostly strikes the people who are already close by.

We've built plenty of substitutes for the hallway. Social media is very good at the low-friction part. You can share something whenever it suits you, and your friend can respond whenever it suits them. What it can't reproduce is being in the same room: a hand on the shoulder or even a handshake.

There are plenty of attempts to rebuild that hallway now. NiceToMeet puts strangers over 45 around a dinner table, while Creative Coffee Club matches creatives over coffee. Then there are apps like Bumble BFF, Meetup and Timeleft [7] [8] [9]. People are clearly hungry for contact. I find it a little sad that we need an app to do what a school hallway used to do. Finding new friends gets plenty of attention. Keeping old ones rarely does.

What Administration Looks Like

It's small and a little dull. A standing dinner on the first Thursday of the month. A text that names a day: “Are you free Saturday at four?” works better than “We should catch up.” The first gets a yes or a no. The second gets “sure, sometime.”

Hall's own advice fits here. You can't make people spend time with you, but you can invite them, and a new setting helps [5]. Try a walk where you used to meet for drinks.

I'm in a group of friends who love listening to music, and we try to hold a music night once a month. We first tried to pick a fixed day, and that never worked out. What we learned is that if we meet in the first two weeks of the month, we're fine.

Another group meets monthly for dinner. I send a poll on a messaging app, and we sort out a time. We almost always go to the same restaurant in the West Village. We know the menu, we know what it costs, and getting there takes almost no effort. Since COVID, people seem more comfortable staying home, at least in my circles, and cutting down the friction is one way to get them out the door again.

I set reminders. I keep a list of close friends, a small CRM of sorts, with when I last spoke to each one and when I should reach out next. AI has made that even easier to maintain. You heard this app idea here first.

The line I hear most from friends I haven't called in a while is “I was just about to call you.” I was on their mind too, and they meant it. Life gets in the way. A calendar helps a lot, as long as you follow it.

Reaching out is the cheapest form of maintenance, and we still put it off. In experiments with more than 5,900 people, those who sent a note or a small gift underestimated how much the other person would appreciate it, especially when it was unexpected [6]. We seem to forget how much a message out of nowhere can mean.

Where It Breaks

Getting a date on the calendar is only the start. Interaction is one part of a friendship. Openness, support and just being good company matter too [4]. A dinner where both of you check your phones adds hours to the count but little else.

Watch who does the organizing. If one friend plans more, that doesn't always mean they care more. Some friends rarely propose a date but show up every time you do. Still, if it's always you, say so once, plainly, and hand over a date to pick. Some will, some won't, and you learn something either way.

In my own circle, there's usually one person who does most of the planning, which is great. But sometimes the place is far from my apartment and it starts late at night. I can't blame him. He's planning something that works for him. I told the group that some events are too far and too late for me. Now we have a pre-game somewhere convenient for me, and then they carry on while I go to bed. I also started planning events myself. It wasn't easy. It's like learning a new skill, but I've gotten better at it.

All this doesn't mean friendship has to become a task list. The reminders, polls, and recurring dinners are just ways of making sure life doesn't quietly make the decision for you. After that, you still have to show up.

Put the next date on the calendar before you leave the table.
