When I was in the first grade of primary school, I was playing with my monitor and several classmates at noon one day. The monitor accidentally pushed one of his classmates to the ground, and that classmate cried with a wow. His head was broken and he bled a lot. We were all frightened at that time. In the afternoon, when the teacher came to class, the monitor put the blame on me, including the injured child. The teacher asked the whole class who did it, and everyone shouted. I kept crying and explaining, but it was useless. The teacher wouldn't believe me. I felt desperate. I was really helpless and helpless. In the end, I took it all. Now that I think about it, I still feel vaguely uncomfortable in my heart. At that time, I was really stupid and cowardly, and I really left a shadow.
