sj, would you be more comfortable writing a letter? (I'm not sure what the best way would be to present the situation in a letter, but it seems easier than a phone call. Also you have the benefit of not being interrupted by the person on the other end of the phone.)
A letter would mean signing my name to it, which I'm not sure I want to do because I'm paranoid like that. I think I will probably call, but I don't know how to phrase what I want to say.
sj, since this is typical behavior for some of these students, this isn't just you being aggrieved (not that you don't have a right to be!); it's a matter of the safety of the students. I would call or write a letter to the principal and just let them know that this dangerous behavior is going on. What they do with the information is up to them. But a kid could get hurt, goofing around like that, or cause serious damage to drivers.
Yeah, that is definitely what I'm worried about. If it would just about some scratches on my car, I would care, but I could have easily hit the girl on Friday, and the woman who hit me could have lost her baby.
