When I walked into the classroom the next day, Zhao Ya and the others did not block me as usual. As soon as I sat down, Zhao Ya wanted to come over and pat my table, but before her hand could touch it, she tripped over the leg of her own chair and staggered. Another girl wanted to sweep my pencil case to the floor, but suddenly she let out an "ah" cry, saying that the pen tip pricked her hand.
