Ben is ten years old. He is a lovely boy, but sometimes he doesn't follow the rules of his school. He often runs on the stairs after class. When he is excited, he jumps in the classroom. He eats candy during the class. And he leaves school without asking his teachers. Yesterday he ran in the wet playground and fell down.

   Ben, you shouldn't run on the stairs. You may get hurt.
