Do Housework

David’s mother is a teacher, and she seldom has time to do housework on weekdays. Sometimes David helps his mother do housework, but sometimes he doesn’t like to do it.

Today is Sunday. David is sleeping. Suddenly his mother shouts at him outside, “Wake up and go upstairs.” She wants him to move the bookcase in her study. She says there is no change in the room for a long time. She is tired of them standing in the same place. Now the bookcase is on the right of the desk. His mother wants the bookcase to be on the left. There are some books in the bookcase. It’s very heavy. How can they move it? “You can put the books on the floor first,” his mother tells him,“You must be very careful.” David puts some books on the desk, and then they begin to move the bookcase to the left. “Watch out!” mother says, “The books are falling.” David picks them up quickly. It takes them almost the whole morning to do it. Mother is happy with the new position of the bookcase, but David is not very happy. He doesn’t like to move furniture often. He likes cleaning the house better.
