David: Hi, Helen. What chores do you have to do at home?

Helen: I have to do the dishes, sweep the floor, take out the garbage and make my bed.

David: How often do you do the dishes?

Helen: Twice a week.

David: Well, you are so diligent. I am really lazy. My room is messy.

Helen: Oh, David. You should often tidy your room and often help your parents to do housework. Then they will be very happy.
