First, students shouldnt have phones on in school. I know though, we had pagers and we always had them on. If your the teacher and a kid says its his mom in Iraq, what are the chances he is being honest? Maybe the kid has a reputation for being a goof/prankster and the teacher just thought he was being his disruptive self? Didnt his mom know he would be in school anyway, seems dumb on all aspects.....
