Don't doubt yourself. You are a good teacher.
I know that your mood is very complex now. It's the anger of hating iron but not steel. It's the sadness that nobody understands. It's the disappointment of students. It's the helplessness of teaching. Although I can't fully interpret your mood, I want to tell you that don't be disappointed. Remember that there are 12 classes behind you, who have always supported you
Once I thought that you were very strict with them, but one thing changed my opinion. Maybe you don't remember: the first two days, I lost my guide case that day. I asked you if there was anything else. I thought you would assassinate me, saying that I didn't attach importance to politics, but the fact was unexpected: you told me to go to your office to look for it, and patiently told me that you were right at your desk Face once teacher Zhang's seat, and finally after I didn't find it, you comforted me and said: it's OK, forget it. Anyway, it's not an important guiding plan. I felt guilty at that time. I can feel that you are very gentle, and remember that you have another action that makes me feel particularly warm: every time I come to ask you something, you will lower your head and turn your ear.
In fact, I think you can laugh more and not make the students feel severe
This is Thursday. I saw you standing alone by the corridor, with your hands on the railing, and looking forward with a solemn face. I would like to send you a letter.
