On the evening of May 2 1, we lost track of time because we were too high to celebrate a classmate's birthday. I returned to the dormitory at 23: 48, and was recorded as late by the dormitory administrator. Our behavior of coming home late has had a very negative impact on the school and classmates, damaging the class image of Class Three. Students should learn from each other, make progress with each other, respect teachers and observe discipline. My own performance has played a bad role for other students and will have a serious negative impact on the construction of the style of study in the class. At the same time, it also caused some damage to the image of the class. We should protect it, not destroy it! For such a thing, I made a very profound reflection on the consequences: it caused a negative impact on my classmates; It has adversely affected the improvement of personal comprehensive level; I also have a deep understanding of the dormitory management system. I also realized the seriousness of my mistake.

I hereby promise myself that I will never come back to the dormitory late from now on, and I will be strict with myself. I want to express my deep apologies to my teachers and classmates and hope to get their understanding.
