Will you tell the teacher? In fact, this question is not easy for anyone to answer, except the big brother of security, whether to tell the teacher or not is his freedom! I don't know if you are afraid to tell him the real lesson or something ... If you tell the truth, you should always hold your heart. As for the "criminal record", this is purely to scare you.
What gives you courage is: what I am afraid of, even if the teacher knows, it will be a batch and will do nothing!
Reminder, the mid-term exam is coming. Let's relax, concentrate on reviewing, and play for another two months after the exam.
