That's okay. You may still benefit from knowing each other when you run out of milk and shops are closed, or whatever favor neighbors can provide via the valuable indirect social graph connections (need a reference for a job or to enter a good uni, ask a neighbor who is a Harvard alum; or just let a kid interview a Republican neighbor for a school essay, or...), so it's good you sounded each other out.

Not everybody has to be best buddies with their direct neighbors, but in my experience in a one-mile radius from you, whereever most of us are, there are some interesting folks nearby that are worth knowing, and they would say the same about you.

Because of TV, social media, computer games and gadgets, we forgot how to socialize well, but if we (enough of us) care enough, we can re-learn it.
