The start of his first semester was a mess. He didn't under-stand class periods. After the first class was dismissed, he would run out to play and not come back when the bell rang for the second period, forcing the teacher to look all over for him.
剛開始第一學期亂得一塌糊塗，他搞不清楚上、下課的意思，第一節下了課跑出去玩，上課鐘響不會回教室上課，累得老師四處找人。
