Waiting for dd2's prescription last night at a pharmacy in a large supermarket and the man next to us was smiling and chatting to dd2 (6months). When he saw I was watching he instantly stopped and said "don't worry, I have two daughters of my own" as though he was expecting me to scream at him to get away from my child. Now it is possible I just have a very scary face but aibu to feel sad that someone would feel they need to justify interacting with a child (or maybe I'm just too trusting?!).
