Lucked out, bought in a new section of a neighborhood, in the front. First 3 houses all in their 30s (we are the 4th). First couple of years we all drank and hung out, then they all had kids. A year later we had a kid, and then they all had their second kid. Now we all throw our kids in the fenced in yard and have happy hours together.
Our neighbor on the next side (5th house in) are 70 year olds who love giving us extra food to eat and watch our cat when we go out of town. Basically nest of both worlds and everyone looks out for everyone else. We do know a lot of the other neighbors too bc it’s so new and people were so friendly. Will suck when we have to move.
