I've lived in the same house I lived in as a kid. And when I was a kid I knew all the other kids and family in my cul-de-sac. but then we grew up and now i don't talk to my neighbors often. though I know them enough that if theres some issue affecting our neighbourhood I can talk to them. and we wave and say hello if we see each other outside. I have basically nothing in common with any of them though. One of our neighbours is a Seventh Day Adventist pastor and his family, another is a family who does real estate and used to own all the land my neighborhood is built on, so they kept what seems to me like the equivalent of about 3 lots and they're constantly building stuff on it and taking my goddamn parking spot.
