I think that a lot of those people likely live in a very car dependent, suburban area, and therefore don’t get any regular interaction with people outside of their immediate family.
I live in a city, so I have regular infractions with people that I know when I’m out and about: I pop into the butcher shop, coffee shop or green grocer and talk to the employees I know. I walk the dog, and run into friends and acquaintances that live the next neighborhood over, etc. People in rural areas usually have similar sorts of relationships with people in the area.
Contrast that with the suburbs, where neighbors may know each other to say hello to, but not much past that, and it’s hard to build any kind of relationship with the barista at the drive-through Starbucks or any employees at the local Kroger superstore.
You’re probably right. I’m in the suburbs and I have to make an effort to do the things I mentioned. It’s part of the trade off for living here.
The sole exception was when we had the snowpocolypse a while back and no one had power. The neighborhood got together at my house and we cooked everything that was going to go bad in our freezers on my grills and made sure everyone was eating for days while we waited for electricity. I still don’t know most of them more than to just say hello, but we came together when it mattered and that was cool.
