It's okay. You forget it after a long time. Me too. I once attended a remedial class and played with my classmates after class. I locked him behind the door (there was a corner near the door at that time, forming a three-shaped shape), which happened to be seen by the teacher. He thought I was naughty and yelled at me. I cried at that time, and then she said I don't have to go to her class in the future ... so, it's no big deal. She also told me that she taught my sister. Where is my sister? But she still thinks that my academic performance is good, but I am a little headstrong. When she said it, she was very angry and didn't go to class ... She still had such a good impression of me. . .
