Dear teacher,

Let me tell you why I have got so many deductions (扣分) for the last four weeks. Sometimes I got up lately. In order not to be late for class, I did everything in hurry. So I often forgot to put all my roommates’ shoes under their bed. As a rule, we should do a general cleaning in Monday afternoon, but I don’t know. Of course I did not go back to the room to do some cleaning. What a shame! What’s the worse, nobody came to help me when I in trouble. I think they are too selfish.

By the way, many of us are always saying the dormitory administrator (寝管员) is too strict with us. As a matter of fact, I have never met such a cruel person. But maybe, she is right. I promise that I would do well than before in the future.
