Mistakenly scratching someone's car
Q: What is the procedure in the following case:
I was at a parking lot. Just as I opened my car door, a strong wind blew it onto the car next to me and scratched the car abit and cracked the indicator light. I was scared and wasn't sure what to do. I considered leaving a note along with some money on the windscreen but I was afraid and drove away. Now it's really playing on my conscience. Please advise.
