Forty-three. That is the average number of friends a person reports having, according to figures that surface periodically in social surveys. Forty-three. Biruk Tessema could count forty-three names on his phone without scrolling hard. What he could not do, on a slow autumn evening after some minor bad news — the kind that doesn't justify a crisis but still needs somewhere to go — was think of a single person he felt easy about calling.
Childhood friendship ran on infrastructure you never built. Someone else's timetable held you in the same room, week after week, long enough for something real to form. School did it. Team practice did it. The proximity was compulsory, so the closeness could be accidental. Adult life strips all of that out and replaces it with nothing, and then hands you a phone full of contacts and calls it a social life. Friendship doesn't decay in adulthood because people stop caring. It decays because nobody rebuilds the infrastructure.

The anthropologist Robin Dunbar spent years studying the maintenance costs of close relationships and found that without regular contact, face-to-face contact, specifically. Friendships drop through the layers of intimacy fairly quickly. A close friend becomes a good friend. A good friend becomes someone you used to know. The process is quiet and automatic and it does not require anyone to be unkind. Distance alone does the work.
So here is the moment Biruk's situation actually points at: you have someone in mind, someone you've been meaning to reach back out to for a stretch of months that has quietly become over a year. Your hesitation is real. You think the gap is now the problem. That too much time has made the first move strange, even embarrassing. You are weighing the cost of reaching out against the version in your head where they receive it oddly. That calculation is wrong, and you probably know it, but you haven't moved yet.
Most people on the other end of that message are waiting for exactly the same thing you are. The gap isn't the barrier. Waiting for the gap to feel smaller is.
