Mean girls

Mojo fell victim to mean girl speak the other day on the playground. It was the classic two against one scenario; to the effect of "You're not our friend anymore" or something much like that. Apparently Maureen pleaded with them, then cried and then told the teacher. When confronted, the perpetrators said they were only kidding. Yeah, some joke!
I realize this shit goes on, especially with little girls, but I didn't expect it from three year-olds. I know that these little girls are not mean (they are actually sweet), and don't understand exactly what they are doing, yet. It does make me happy that Maureen finds it easy to interact with others. We are trying to instill in her the need to diversify. I told her that she is exceptionally good at being able to play with others, and that if someone doesn't want to play with her, she can find plenty of kids who do.
I realize it will get much worse, when the mean girls realize what they are doing and purposely go for the jugular. I hope Maureen understands that she can rise above these petty insecurities, that she can be herself, and that people will like her for her wonderful personality.
I hope she doesn't become a mean girl herself. Mean girls suck.
