You know, I've lived in the suburbs more or less all my life but I think I'm just now starting to experience suburban living.
From the time I was a toddler up until about a year ago, more than half the houses on my street were relatives, and the only house we shared a border with that wasn't separated by te road or 100 yards of woods was my grandparents' house next door, which we always had access to all the time. Now that my grandparents have both passed and the house has been sold, we've got new next door neighbors.
I've had to physically stop myself from cutting their grass, getting their mail, cutting through their driveway to get our mail, dumping yard clippings in the woods behind their house, all out of habit. Probably shouldn't piss in the backyard anymore either.
