I was parked next to a drive way, in parked postion and getting ready to leave but when I saw that the other party was backing out of his garage, I held off. I waited for the other party to see if he was going to completely back out of his drive way but he held off therefore leaving the back of his car in his drive way just right where the sidewalk was. So when I was getting to leave he also managed to back out and leave too therefore scratching his left side door against the back bumper on the right side of my vehicle. If I had backed into his car, there would have been a dent on his car, but in this case he tried to completely come off of the drive way therefore scratching his car door.
