oh gosh, do I hear you loud & clear! my dd is in 8th grade, and last year and this year have been so awful! The mean girls, also seem to be the ones that are dating, texting boys 24/7, going out on Friday & Saturday nights w/o supervision and I'm sure a slew of other things. Does your dd have a good solid group (even a few) friends she can rely on? Mine is also in band - thus just making the mean girls meaner - but she's got 2 really good friends & they tend to stick together big time. I've always told her, you don't have to listen to her, you don't even have to like her, but you can't be disrespectful to her or anyone. If anyone ever does anything you think is harmful, dangerous, or threatening, you tell a trusted teacher immediately, or tell me. But if it's saying stuff that really isn't important anyway, walk away...turn your back and talk to your friends. It is hard - from what my friends have told me, it gets so much easier in HS, the girls are over the "mean" stuff, yes there are still mean girls, but they all hang together so they don't have time to mess with the normal girls.
just today....dd came home and told me about something that happened at lunch...she was in her locker getting her books & was running a little late...when a 8th grade boy walked down the hall & saw one of the "mean" girls walking the other way...she asked him "are you going to lunch?"...he proceeded to say "only if it's you"...& grab her butt......THESE KIDS ARE 13 !! My dd was grossed out by the whole thing thank goodness!
