Hello, Tony. Let's play a computer game.
I'm cooking lunch. Are you hungry?
Sorry, I can't. I'm busy.
Yes. I want to have lunch.
What are you doing?
It's Sunday today. I don't go to school. My father and mother don't go to work. We are all at home. We are busy now. We are cleaning our house. Look! My father is sweeping the floor. My mother is cleaning the windows. I'm cleaning the desk. What's Mimi doing? Oh, she's playing with a ball. She's my lovely cat. We're tired, but we're happy.
