The cities and the countryside, actually. In rural areas, you may spend most of your time in your own territory, but when you encounter other people they'll probably stop and chat. (For one, when your cows get out and into your neighbor's field for the 6th time that year, you want to be on good enough terms to be able to go fetch them back...)

Suburbia is where we can have exactly what we think we want, and thereby discover that we're wrong.
