First I am sorry this happened to your son. I do have a few different points to make. I am 34 and if it happened to me in the store like a pp said I honestly would be shocked but probably not make a big deal. I was hanging xmas lights on a huge window at work one year cars outside were stopped waiting for a light and my boss (female) pulled my pants down(my undies stayed on) I could do nothing but laugh it really was funny. That being said if this were to happen to my daughter (who is 11) I would probably be beyond upset. I think it is different happening to a child as compared to a grown up(not that they wouldn't also be embarrassed I just wasn't) especially at that age and to have everything pulled down. Also when I was in middle school (this is in the late 80's) a boy did this to a girl and I'm sure at that age he didn't think about it or mean alot of harm (as kids aren't the most mature at that age)but the girl obviously was devastated. Now if this wasn't a big deal why do I remember it all these years later? And it wasn't me it happened to. So it is a pretty big deal. Other kids won't forget this so easily. The boy by the way got expelled. One thing about in school suspensions. I don't know how it works at every school but I remember that being a better punishment for some kids because if they were suspended to their house and the parents worked they were on a free pass for out of school do what we want time. I don't know that I'd get the police involved but if you feel that is necessary you shouldn't feel at all bad about it. Sounds like the school isn't going about this properly especially without even notifying you. Sometimes you have to do what you have to do especially when it comes to your children.
