Well do you?

We don't know neighbour's names at all..those that live on same floor as us. We live in a highrise condo building. We do know the permanent security desk staff and they know us by name. It's always been important to know for emergencies, etc. It's been helpful in the past.

For some people, this type of distance/anonymity it is very bothersome. But for myself, as long as neighbours are quiet, respect the common property areas, it's not a problem.

I just came back from an annual barbecue that our building community organizes. It was pleasant.

In the previous building, I've knew 1-2 other neighbours living on different floors. In last building where I lived, I got to know a couple in their late 60's..who cycled. I met her in the bike storage rm. and we would greet each other as cyclists.

My partner doesn't care much either to know others in building. We both have friends elsewhere in the city with whom we each share more of ourselves and do stuff with them as a couple/individually.
