The following is all a scene, really useful if I was in junior high school in the first place would not have classmates because of school violence jumped to their deaths. If the school loves its reputation so much, why don't they just expel the school jerks? Instead of writing a demerit, saying they're going to expel them, and then finally having the parents buy them a meal to settle the matter. Teachers are also on the principle that more is better than less. When things go wrong, each of them will be beaten forty times, but when nothing happens, even if the bullied person is beaten and cries, they will turn a blind eye to it. Even if the teacher to reflect, but also on the verbal education of the abuser, the abuser was abused after the abuser's retaliation.
The teacher's favorite phrase is "Why didn't you tell me earlier?", but even if you had told me earlier, you would have had a better chance of getting the message across. What can you do to punish the abuser in a meaningful way?
