I cannot really think of much but here goes:
Got into a fight in 5th grade and kicked the kid while he was down, in the face.
On accident, I kicked a piece of ice during winter in the courtyard and hit a kid right between his nose and his right eye. I was a massive gash. That was 7th grade.
Same year I was playing tennis with a friend and we lost the tennis balls but there was construction going on so we started hitting little stones over the fence. I didn't realize there were parked cars on the other side. I dented up a few Hondas, a BMW, and broke the back window of a Lexus and some Chevy.
Oh and came out of a pub, pissed out of my head and decided to piss on a Focus RS. I did that where the windscreeen meets the hood and whatnot. That car must have smelled for a while.
