My dd is 14 and quite a happy and popular girl. However, one of the girls in her class is having a party and all of my DD's friends have been invited except her :( She is hurting and feeling confused and upset. She is uncharacteristically angry and taking it out on all of us at home. Help !! How should I be dealing with this? I advised her to steer clear of the girl in question in future, but she wails that all her friends are this girl's friend to too…..what's the best way to get her to understand that this is a life lesson….and she needs to take it on her chin and move on….
