The alarm finally stopped going off but then he started writing on the car.

Redditor Wakaranyo claims his friend "came back from an overnight shift to find this message written in permanent marker on his van." What he doesn't explain is where the hell the friend gets off letting his car alarm beep for "20 hours straight." People need to sleep! The clear hero of this story is John, who hardly needs to sign his note "sincerely" since he is clearly entirely sincere about putting his dog's shit on the van's door handles. With all that noise, I'm impressed John could think straight long enough to locate a permanent marker and brainstorm all these great ways to handle a problem with a neighbor.
