My dd is in a close friendship group with 2 other girls at school and they play nicely and do everything together at school.
However, when they get home, one of the other girls always rings my dd to talk and bitch about the third girl.
I'm really uncomfortable sitting there listening to them be unkind about the 3rd girl. Especially coz I know they are gonna be sweet as pie to her the next day.
Should I say something, and if so, what?
