I would say not to ask anyone about it or talk about it at school unless someone says something to you. If it is a joke, you don't want to seem out of the loop :). If he really did pass away, and I hope he didn't, just know he's in a better place now and isn't suffering anymore. I hope this helped.

it was true, and sorry for the very late response, i lost my laptop but i found it. but yeah, it was really sad to go back to school, everyone was crying and im better now. I went to the memorial service for the students and teachers and they passed out bracelets and i haven't taken it off for more than an hour since ive put it on.
