Girls are Mean...

Why are girls so mean to each other? I mean really. They start in elementary school and seem to continue through the mothering years. Boys aren't like that. Or, if they are mean to each other, they have a fight and are done. They're buds again the next day, but girls can be evil.
The Social Butterfly is a nice girl. I mean, really sweet, good tempered, friends with everyone. She has two very best friends (who are making an inordinate amount of noise in my living room right now!) and many other friends. Tonight she was at a birthday party of another friend with several girls from school. One of these girls is a bitch. I've known her since she was in Kindergarten and you could see it then. She's always been a"mean girl". For some reason, my daughter was fascinated by her and has been good friends with her since the beginning. I've never really voiced my disapproval of this girl but I've done what I can to encourage other friendships. Well, tonight the Social Butterfly learned a hard lesson. The bitch was mean to one of the best friends. To the point of making her run away crying. At a birthday party. And then when asked to apologize was even meaner. And I learned something new about my daughter. She may be nice, but she's fiercely loyal. I don't think I'll be needing to worry about that bad influence anymore.
