我很讨厌我的室友

When I went back to the dormitory to sleep at noon today, I untied the red scarf and put it on the bed as soon as I came back. Then I lay on the bed and got ready to sleep. When I was about to fall asleep, I suddenly remembered that I would be on duty in the dormitory today. I took a broom and began to sweep the floor in the dormitory. However, my roommate, Li Chenshuo, turned over my quilt while I was on duty. When I went back to bed to go to sleep, I found that my back had been turned over. I asked the person next to me, who turned over my quilt? The man next to me said, "It's my roommate Li Chenshuo." I was angry.
