I lived in a house until young adulthood. What I remember of our immediate neighbors is a young couple with a son and a vicious dog named Shadow and a wealthy elderly couple, on the other side of our house, who always owned Cadillacs. The woman was lovely and the man was a cigar-smoking braggart. I, also, remember good relations between my family and our neighbors.
When you live in a high-rise building, you experience a wide range of types, some of whom aren't all that desirable as neighbors. Since I live on the ground floor of my building, I mostly experience my neighbors in the laundry room.
