Today, I wrote this critical letter with a heavy heart and regret. I'm ashamed of my behavior. As a monitor, I not only failed to take the lead, but also made such ignorant behavior, but the mistake has been made and it is useless to regret it. I will use this kind of self-criticism to remind myself, supervise myself and be responsible for my actions, and I won't repeat such things again.

I don't mean any harm to this matter. I was just too playful and made a joke. There is absolutely no other meaning. But this joke is too big. I regret that I didn't consider the seriousness of the matter. I didn't expect it to be a big deal in the end. I know regret is useless. What has happened, I can't change it. But after I can change, I will let everything I do in the future be considered, and this will not happen again. I don't say that as a monitor, even as an ordinary student, respecting teachers is what we students must do, and it is our most basic responsibility and obligation. Although I didn't mean to, I was still wrong. Not only did I fail to respect the teacher, but I also failed to fulfill this basic responsibility and obligation. I also set a bad example in front of the whole class. I am deeply sorry for this, and I hope the teacher and the whole class will forgive me.

As a monitor, I think I should take the lead and lead my classmates to be their role models. But I didn't do it, and it became a negative textbook. I know my classmates know what is good, what is bad, what should be learned and what should not be learned, and how to distinguish between good and bad. Therefore, students should learn from the advantages of others, check whether they have such shortcomings when they see their shortcomings, and correct them. Let yourself have a wake-up call to remind yourself.

I am very grateful to the teacher for choosing me as the monitor, placing great expectations on me and giving me such a good opportunity to exercise and improve myself. But I failed to satisfy the teacher with practical actions, and even failed to do what a monitor should do because of my bad habits. I have realized my mistake and am determined to correct it. I hope the teacher can forgive me and give me a chance to correct.

I know that the review is not necessarily from the heart, it may be just to deal with the teacher, or it may be hypocritical, because the review is just an ordinary piece of paper, and correcting mistakes depends not on writing a review, nor on talking casually, but on practical actions! Only by recognizing your mistakes and correcting them can you be worthy of yourself and this review. At the same time, we should learn a lesson and take this review as a wake-up call. A supervisor should always remind himself whether to do or not to do everything, what the consequences will be and be responsible for what he has done.
