I strongly agree that neighbors ought to interact more. Yesterday I greeted neighbors moving in.
I was the only person I saw do that.
It's a shame, and it's possible that social media is part of the problem. I saw a reference to a social media site (sorry, I can't recall the name atm) that was based on neighborhoods, and I hope this is a step in the right direction.
Thanks!
I started introducing myself to my neighbors a few years ago, and I'm so glad I did. We all help each other out now, with vacation mail and repairs and that kind of thing. It's weird that there used to be a time I'd share a wall with someone and not even know their name.
