My son was in his second year of junior high school and was dragged into the toilet by senior studen

This matter needs to be verified by the teacher, the whistleblower and your doll, and the student must act according to the school's regulations.

This shows that you are very sensible and do not care about him in general, which means that you are smarter than him, open-minded, and listen to you to solve it violently? Violence is not the best way to solve it, now is a society governed by the rule of law, you can't fight, fighting and fighting is the most unsober time for your brain, in case you want to lose your mind and start heavy, it was his fault before, he was injured, and in the end you suffered, it's best to talk to you, if you shouldn't be in this way.

This kind of thing, just rush out and flush it out to the toilet and pull it back, not to mention that if you tell your parents about this kind of thing, your parents will only help you, and they will never say that you are not.

I believe that the school will deal with it, report it to the teacher, or call the police to deal with it.

Don't think about whether you're going to be bad, you're right, and that should be the other person's question.
