Do you always talk to your neighbors or keep to yourself? What about neighbors without kids?

When we were moving out of our house last week our neighbors from across the street who we thought we were on good terms with unloaded on us for ignoring them and being “private people” during the 3.5 yrs we lived there. I was totally shocked since 1) I don’t consider us private at all and frankly remember waving to them almost daily and 2) is there really anything wrong with being private? Aren’t most people to some extent? I mean there was a busy street between our houses and they were empty nesters with lots of time on their hands meanwhile I was constantly chasing my 2 small kids out of the street and back into our house. I thought our actions were self explanatory but maybe not.

Anyway how private are you and do you always make time to talk to neighbors?
