I owned for the last 25 years (3 houses, 8, 8 and 9 years) and am very social person. I do not have a single neighbour friend in all these years. what you are describing is (in vast majority of cases especially in urban areas) just wishful thinking.

This was also our experience while owning three homes in single-family neighborhoods over a 35-year period. We knew our neighbors enough to say "hello", but that was it, and we never associated with them. However, 13 years ago we bought an apartment in a large high-rise condominium building. To our surprise - because that was not a consideration when we moved - we have made many good friends among our neighbors. We go out to dinner together, we invite each other to our homes and to family celebrations. The downside is an aspect of communal living. For example, we needed a new carpet in the building's lobby, so all the owners voted on the color. The majority chose green and we hate green, but we have to live with it.

Counterpoint in Seattle - We talk to our neighbors regularly and are good friends with a few. Having kids helps.

yes, because he forgot about the car. The reason we don’t befriend our neighbors is because as soon as we leave our home, we put ourselves in a metal cage, ensuring no one will talk to us if we don’t want them to.

Befriending your neighbors kind of works in a city but only REALLY works in Amish communities.

Disagree that it's wishful thinking. Making friends with your neighbors requires a commitment to community - it has less to do with being a social person and more to do with recognizing the mutual benefits.
