I live in a small town in Poland and when I was a kid, my whole street was a community. My parents were friends with all the neighbours (some less than others, but still). My mom used to host "coffee time" every other day around noon were women from the neighbourhood would gather for an hour or so to gossip around coffee - of course me, as a kid, just lingered around them.
All the kids on the street hang out together, playing games, kicking some soccer ball, going to the woods, etc. People on the street were so close together that it was possible to organize "cleaning the street" events from time to time where everyone would gather up with their gardening tools etc and we would just go through the whole street, cleaning up overgrowing grass, cutting out weeds on the forest border, etc.
I must say, looking back, this was a wonderful time and a GREAT environment to be raised in. I think that being a part of a small community like that is really important for mental wellbeing.
Unfortunately, all of that pretty much died along with my mother and grandmother. Other elderly people on the street died as well, the community loosened up, new people moved in and I rarely see them or know their names, they are not interested in random chatter on the street (at the rare occassion you ever meet them outside the house) and I don't have the courage to pick up my mother's wonderful idea of "coffee time". A bit of a shame, but I'm still trying to get to know the people around my place. The way things are going here in Poland, I might need to pick up Duolingo and launch some Ukrainian course though :)
Anyway, just venting
