that's horrible that you have to be on your guard all the time. I think that kids have become more prone to violence perhaps in part because of the fact that there aren't any consequences. When I was growing up and in in either 7th or 8th grade, there was a kid that was a bully to all of the teachers and disrupted every class he was in. He was soon expelled and as far as I know all the teachers and administration were in support of the teachers as were the parents. These days I think that support would immediately shift towards the students regardless of how awful they were.
I don't envy that you are in education now pal, I am really glad that I am not, no offense intended of course.
