What the hell is wrong with you?

Someone keyed my car the other day. It was parked behind the bridge club in town, got off work and BAM! A big key line on my door. What kind of thin streak of piss did would do this? No balls prick. It's not even a nice car, it's a piece of shit corolla with different coloured panels. Did it offend you? Is that why you felt the need to vandalise my property? Screw you.
