That's not a universal truth. I grew up in the suburbs and I've lived in a city for my whole adult life. I feel a MUCH stronger sense of community in the city. I know so many of my neighbors that it's hard to leave my house without running into somebody I know.

It's funny that as a child in the suburbs I had maybe 10 neighbors within a half mile and we only knew 2 of them. I never saw them. There were no sidewalks and people didn't walk around.

In fact, in our typical suburban boredom, sometimes we'd sneak around our neighbor's properties to see if we could learn who they were. We were pretending to be spies. One time we discovered that our closest neighbors had goats and we were blown away. I never did meet the people living in those suburban houses in the 10 years we lived in that house.
