Hello! I am a sub, and I need your help, please! I had a student who threw a sarcastic and offensive comment about his regular teacher's physical appearance. This has been done in the front of the class. He just shouted out,"She has a......!". I said,"This is not appropriate, you can not say such things." He had agreed, but in a while he repeated the comment looking straight at me. So, I had reported this to the office after the class had been over. The office later said they called the student for a talk. But the sudent said he did not make such comment, and that I must have been mistaken him for someone else because everybody had been talking (yes, we had a discussion, but it was not too loud). This student is already known in the office, and I had also experienced him "flipping" a situation or a word, so he comes out innocent and the opponent comes out guilty. I do not want to drop this school, the school is wonderful in general. And, I do not want them to drop me. What is the best way to act with such 8-grader next time he tries to instigate me? Thank you very much.
