That happens when the boys are underestimated. and it is thought that everything is revealed. but I think that the authorities are not only responsible if the students feel that fear should speak with their parents about it so that they as adults are the ones who speak with the teachers and so they can also help to disernir if these children have any reason to be afraid or if it's just paranoia. On the other hand I dare to say that education is failing from home is to say that parents should be more aware of their children talk to them who think. Surely more tragedies could be avoided if all together make equipment. It is my humble opinion.
