We have some "shitty" neighbors letting their dog shit on the sidewalk. I stepped on it trying to walk to the end of my block and not noticing until I came back. I'm having plans of wetting the poop still on the sidewalk and putting it in the mailbox, throwing it at the door or smearing it all over the porch. Perhaps this will teach them a lesson on how not to ruin expensive shoes. What is your experience with bad neighbors?
