(This all happened in the school parking lot.) I saw my friend in his car after football so me and two other kids ran up to get a ride and they grabbed two of the handles and he reversed really fast, then I ran up seconds later when he wasn't moving and I got in front of his car and he was about 10 feet away and then he went forward at about 7 mph and when it was like 6 inches from my shin i got on top of the car to stop from being ran over. I dented his car. Who is responsible for the damage?
