Um ... . . . Actually, I'm just like you. I'm from grade five or six. . . . . . . You can run faster after class, no, soon, occupying the back or side position. Our school is in a vertical row. I always sit last, avoiding changing, and deliberately exposing my elbows or feet, so that when there are no people or few people, others will not look at that position again. In fact, this should be changed anyway, otherwise it would be embarrassing to get a stool at school. . . . . . . . . .
