Suburban bourgeoisie. Making the common choice, not because it's the most interesting option, but because it's easy. When you no longer feel the need to question the norm, when you are fine with the status quo, when you accept the accidental form in which your life has solidified without worrying about all the unexplored alternatives. And the fences... those eternal wooden walls with which we mark our territory. Mine!
The perfect metaphors for our narrow-mindedness.
