immaturity

I have never been so frustrated with an 8th grader's lack of maturity as I am right now. I'm at school...sitting in my office during my lunch break because I need to calm down. I'm so frustrated and angry at my 8th grade class that I want to spit, or curse, or kick something. I can feel the anger making me tense. Why? Why can't they just act like normal human beings? Why can't they just act like they are in the 8th grade and not like they are still wearing diapers. I feel SO sorry for the few in the class that know how to act with decorum. I want to hug that few.... if only they could influence the rest.
