Yup. Small, quiet barber shop. Big fella gets out of barber chair and my 3-year old son yells "Mom, that man has a huge baby in his belly!"
Man pretended not hear and walked out. I wanted to die.
All you can do is explain it's not nice to talk about appearances, but it's really hard for kids to get what's insulting or not for a while until they are a little older, and stuff is bound to happen. :(
Oh, and the best was we were behind some college kids at an ice cream stand, and my son was eye level with all the girls' butts in Daisy Dukes, and the one right in front of him had white daisy dukes. My son put his little finger up almost to her "goods" to point and said, "Mom! Look how SHORT her shorts ARE!!! They are so short! I can almost see her bottom!!!" Since it was a crowded setting, I ignored him at first, but he just kept getting louder about the REALLY SHORT SHORTS so I had to poke him and shush him etc....
