how many hours does it take to make a friend?
the 200 hours
Jeffrey Hall's 2019 study put rough numbers on it: around 50 hours together to move from acquaintance to casual friend, about 90 to a real friend, and more than 200 to a close one. Hours of actual time, not good intentions. This is the least romantic and most useful fact about adult friendship. School and university handed you 200 hours by accident, in corridors and lectures and all that dead time between things. Adult life hands you none by default. So making friends after about 22 is not harder because you got worse at people. It is harder because the hours stopped being free and nobody said so.

why is it so hard to make friends as an adult?
Because closeness runs on repeated unstructured time, and adulthood removes the structures that used to supply it for free. The fix is unglamorous and it works: pick a recurring thing with the same people, and let the hours accumulate. Frequency beats intensity every time.
