i feel sorry for your neighbor. just yesterday i watched a dickhead neighbor of mine allow his unleashed dog to take a whizz on my mailbox and the $30 in plantings that surround it. I made sure he saw me watching through the window; next time i'll be outside having a face to face and if that doesn't work i'm calling animal control (this dumbass apparently doesn't believe a leash is necessary for his special doggy).
it is beyond me how some people feel the rest of the world owes their little fuzzy poo or tinkerbell the ability to wander freely and whiz/crap at will. can't control nature my ass
