Must be a cultural thing, but no one in my country (NZ) has ever said a negative thing about our boy (who is now five). Once or twice someone has asked if he has had any health issues, but that is very rare. Not too infrequently people say positive things about him, sometimes extremely positive.
Once or twice people have said odd things, but certainly nothing to make me crazy. For example one person once asked if our five year old 90lb boy was a puppy! (Wonder what he would have been like fully grown then!) And once or twice people have asked if our boy is male or female.
