Actually, it wasn't even me insulting my children, it was the kids' aunt, but I am 100 percent fine with it.
Scenario: Kids and Auntie (childless) are at the park. Kids are jumping in muddy puddles. Auntie tells them they are "diiiiiss-gusting!" in an over-the-top teasing tone. Two women are passing by and one draws a hissing breath and says to Auntie in a disapproving tone with a disapproving look, "Ooooh... you need to be careful about talking to them like that."
AIBU to think this lady needs to remove the stick from her ass (and her nose from other people's business), or is it really not okay to tease children with whom you have a loving relationship these days?
