I can tell you are a girl without telling me. Actually, your sense of responsibility is undeniable. The head teacher doesn't like you, it's just your imagination. Perhaps the class teacher is really not satisfied with your mistake, but adults will not be so intolerant. As long as you continue to work hard and meet people for a long time, the class teacher will understand your pains. Nowadays, boys and girls in society are more active, and besides, they are too young to be so sensible. No matter who is the monitor, the phenomenon you mentioned will happen. I think you should keep doing it. Be a monitor, be both rigid and flexible. You have offended your classmates, and it may be more difficult for you to carry out your work in the future. It's really your fault that you don't report the situation in class. You can tell the teacher that as long as you communicate well, the teacher knows well. Stick to it, the more you do this, the more you have to change, and you will gain and make progress. The more so, the more you should be a good monitor and prove it to the class teacher.
