So, we live in a small town not some crazy busy city. Every time I take my son into walmart now he asks strangers for a fist bump... should i correct him amd say thats not polite? he does it with a huge smile and holds his fist out to people and says knuckie "knuckles". Im a ftm and not sure how to approach this lol he even does it to elderly women and they do it back and smile. One older gentleman did it 3xs for him becaise we passed him on 3 seperste aisles! I feel like im damned if i let him and mean to him if i do not let him.
