I was out shopping with my friend and baby, she had driven us in her car. at a carpark, when we returned to our parking space the car beside us had parked over the line into our space on the side with the car seat, thinking I could still get my child in I opened our car door and unfortunately it did a small dinge, when I checked the other car there did not appear to be any dents but the smallest dot of white paint from my friends car was there. My friend said not to worry and she backed out of the space to let us get in safely (something we should have done from the start). There was no one in the other car and my friend drove off but now im worried we'll get in trouble or that someone will have saw us and report it? AIBU for worrying, friend doesn't seem bothered!
