Totally valid observation, but things definitely changed. Neighbors don't know each other as well, so the grandma keeping an eye out the back window doesn't exist anymore. It was a village watching the kids before, its not that way now.
Similarly, I expect most kids in a classroom to know of each other, but I doubt they all know each other. If that makes sense. Such that, it is easy to think this is also a by product of how much more you can do inside your houses? Back when you would see folks outside more often, it was common for you to know of a lot of people. If you only had a few "shut in" type people, you knew them as the shut in type people. As it becomes more and more of us, it gets tougher.
This, over time, leads to familiarity with those around you.
Now most people would be highly suspicious if you sit in your front yard.
Or maybe kidnapping paranoia fueled by years of crime news programs?
IME while church might be a community, it's really a very stifled one.
Right, this is what I am wondering, is the reason people were comfortable doing this the fact that there was a weekly touchpoint with the community? The church visits might be stifled but if they establish a relationship with that large group of people then that might enable more free roaming at other times.
