Something similar happened to me with a neighbor’s car. I turned too wide into my parking space and ended up bumping the back of my neighbor’s van, leaving a noticeable mark. I immediately went up to their door and knocked to apologize, but no one answered AFAIR. I decided if it was a huge problem, they’d come to me or my dad about it, but they never did. So technically I wasn’t forgiven, but I wasn’t reprimanded either.
