What is up with millennials not wanting to get to know their neighbors?

As a millennial, my wife and I moved into a mixed ave group neighborhood a few years ago. Over the years we’ve made a few friends with our neighbors mostly older like boomer or Gen X.

But recently we’ve also had a few millennials move in after a few out of our neighbors sold their houses. And I’ve noticed that these millennials are all super antisocial. They literally come home, park their cars into their garages and never come out other than leaving the house to go somewhere or maybe mowing their lawn.

And I’ve even noticed this even when I was in college living off campus in houses. Nobody ever knew who their neighbors were or even cared to know. Even when the house was a duplex.
