My DD9 (almost 10) has been acting like a teen all week, very moody and cries easily (a little early for this, I thought). Anyhow, today, she came home in tears (she's had practice after school most days this week for a performance). Here's what happened today: Another girl (a year older than my DD) got really mean with her at practice. My DD accidentally stepped on her foot and she told her "If you touch any part of my body again, I'm going to rip out all of your hair"...then, she took my daughter's hair in her hands and then let go of it and said "no, I'm not going to do it this time". I asked my DD what she said to that and she said nothing. My DD is super sweet and pretty shy, and a little clumsy too. I think this girl must have something to do with my daughter's mood all week since they've been together for practices everyday after school. They have to spend time "in the wings" waiting and she's right beside my DD. Anyhow, I can't sleep. I'm mad. The performance is tomorrow night and all I can think of is "should I say something to the girl to warn her that I know?", should I take her mother aside and tell her and let her handle it...and possibly make it worse for my DD. I hate conflict, and I know this is the first of many that I will have to deal with...but what's the right thing to do? It's almost 1am and I can't sleep!
