I like that our cultural norm isn't faux positivity and formality. I grew up in a very cohesive urban neighborhood in Seattle where I knew nearly all the neighbors on the block. There was plenty of social interaction without what I consider to be odd cultural baggage.

I was allowed to roam the block freely as an elementary school aged child (it wasn't that much of a simpler time there were weirdos around and we knew to leave the needles alone). As I grew older I watched their kids, mowed their lawns, and took care of their pets. The spirit of mutual assistance was pretty real, we kept a few neighbors in their homes well past the time they were capable of fully independent living. If something was ever amiss my parents either had house keys or could figure out who did.

I see this as being a functional society. Greet your neighbors, pet their dogs, be obvious about participating in trick or treating, etc.
