For me it is a combination of age, having kids, having moved around, and general deterioration of the social fabric. Especially church-related events are mostly absent in my social circle.

But boy am I glad that I took the decision to join a "Studentenverbindung" (fraternity) in my university days! Three times per semester we put on suits, sit around a long table, drink beer, and sing nonsensical songs. This has been going on without fail for 140 years -- well, almost without fail, there were gaps during ww1, ww2, and covid. I go to about 1/3 of these events. I meet my old university friends, their families, and a bunch of young students. I expect to continue doing this for many years to come.
