I am Cindy. I have a happy family. Tomorrow is Saturday. My grandpa is going fishing. He is sixty-two years old. My dad is a businessman. He is fat. He wants to lose weight. In the afternoon he is going to play ping-pong. My mom is beautiful. She will cook a big meal tomorrow night. So she'll go to the supermarket and buy something. I am a good girl. I should help her do some housework. Am I helpful?
