Picture this... I parked my car always leaving more space from the neighbouring left bay so I can open my rear left car door more easily to get 10 mo DS in and out more easily. While we were away from the car, a car parks in the bay to our left but occupies more of the right side of their bay leaving little space for me to put DS back in the car. There was also a van parked in the bay to our right. So when we returned to our car I carefully opened the rear left door and put DS in his seat. As I was doing so though my hip touched the car door and the car door touched (not bashed) the car to our left. I wasn't worried as it only touched and when I glanced to check I saw no damage. I got into the driver's seat, shut my car door, connected my phone to the car... and then I got a knock on my window. "Can you come out please" said a straight faced middle aged man. "Can you open your rear door so I can check something" I guessed where this was going and so I did. "Thought so. I'll take your name and number and I'll send you the bill". I was shocked and had to bend down and inspect his car door closely. Sure enough there was a small white scratch mark; barely noticeable. I gave him my details, apologised while looking and feeling baffled and left. Upon reflection however, I realised that this is likely to happen again and there wasn't much I could have done differently given my 10 mo passenger's safety needs. Therefore, as a mother I'm probably doomed to paying very high car insurance with all the claims I'll be making while working reduced hours and having a million other things to worry about or AIBU?
