My daughter and her three best friends have been close for years. There is another friend who they have all been spending more time with. This girl organised a band for the school music festival with my DD and her three friends. A few weeks ago she told my daughter she was out of the band, and keeps the other girls on their toes by switching favorites, and deciding who is in or out as she pleases. The other girls realise what's happening, but seem so grateful when the "queen bee" lets them "in" that they won't stand up for themselves, or for my DD. A few days ago she made some horrible comments about my DD's appearance. My DD feels she has been isolated from her friends and thinks that this must be due to her being "less pretty" than the others, which is absurd. My daughter is in fact extremely pretty. I have let this run its course for a while, but it is affecting her confidence now. I don't know what to do as they are only 9!
