When I was younger, I liked to be bad. I always played rough with other kids, and I found a special entertainment in them getting hurt. I didn't outright hurt them, I learned it early that adults would scold one for that. So just played rough, and waited until someone would get hurt, and if no one did, I would accidentaly run into people hard, so that they would.

When there wasn't anyone to hurt, I would break thing. Dropping a plate here, stepping on the flower there....
