The suburbs are different. I may not be thrilled when someone knocks on my door to ask me to vote for them, or whatever, but I don't feel like they've violated my space or anything. My door is right on the sidewalk, which conceptually makes a difference as unlike in the burbs you don't have to actually walk onto someone's property before you can get to the door. Well, other than the stoop.
Anyway, too late on a Sunday for especially deep thoughts, but we do interact very differently to our geographic spaces and to each other depending on how things things are organized spatially. It matters, perhaps a lot.
