I had just popped into the supermarket today with my two DC. My DD opened her car door into a vacant parked car next to us causing a small ding (size of a one pence piece). I didn't have a pen so we went into the shop. When we returned to the car a short time later to leave a note on the windscreen it had gone. As i had the children back in the car I drove home and immediately called the supermarket and reported it leaving my contact details. AIBU to think i have done all i can?
