Yesterday morning I became the first to come to classroom, and to my surprising, I found my bench broken. As there was everybody around at that time, I immediately changed bench with Li Kang, of whose seat was just behind mine. Five minutes late, Li Kang came in. Seen the broken bench, he could do nothing but stand listening to the teacher during the first class. When the class over, he carried it out and began to repair it by himself. My face suddenly turned red and I kept silent in my seat. You can never imagine how regretfully I felt for that I had done.
