Long term lurker but I could really do with collective wisdom so braving it on AIBU. My DS 10 was out with my Dsis and DD (plus family friend). They were in a sport shop. DS wandered a few yards away from the others to look at something but D still visible. Without any warning an offer man passed my son and as he did so he pinched my son's cheek hard. The man then walked away. DS didn't mention anything straight away but he was obviously quite uncertain. By the time he said anything the old man was long gone.
I had an aunt who did this to me when I was little and I hated it but there's something about the fact this is a stranger touching my DS that I find really creepy and it feels almost predatory.
Am I overreacting?
