WHAT WOULD YOU DO???

I'm still trying to come up with an opinion on how I feel about this. I'm also trying to think about what my response would be if somebody cut my daughter's braid off b/c she was playing with her hair in class. The easy response is to say I would "snap" but that's what everybody says and then when the situation arises they do something totally different. So with that said, I am not sure what I would do. WHAT WOULD YOU DO??
