Let me take it a step farther. We live in a relatively new subdivision. It's part of a planned development. We were one of the early group of buyers in this particular section. In four years we've only met maybe 15 residents who live around us and only see about a handful of people when we're out and about.
I'm old enough to remember when you knew just about everyone who lived in the neighborhood. You may not have agreed with them on everything, but you knew their names, their kids, and would occasionally share a drink on a front porch. Porches have been replaced by backyard patios that are surrounded by fortress like fences. The local "social committee" has a hard time getting folks involved in activities.
Unfortunately most of us live on social media where it's extremely easy to air our grievances anonymously. And in doing so seldom allow for civil discussion over sometimes trivial issues. Especially ones where they usually have no real insight on the reasoning behind the decisions, only they don't like it.
