Moved into a new apartment was backing up and heard a like bang noise. I was close but am pretty sure I didn't hit the car i brakes fast and the soda cans in my car hit moved in my car. I got out looked and saw no damage on the car and mine was fine. What do I do??8 had to get to work so I left. No one was around me I don't think they had cameras. I'm scared cause my parents pay not me. Am I okay???
