We once found a local dog walker smashing down some of our building work on a Friday night- when confronted he said we should have something better to do with our time- it was, however, quickly pointed out that he was the sad bastard out on his own on a friday night smashing up people's hard work. We had to hold back one friend from killing the bloke and his dog- thankfully neither have been seen since!! You're always gonna come across narrow minded and truly pathetic individuals- good luck with your battle...
