One day, a little girl went to the park with her grandma. She saw many old people in the park. Some of them were doing taijiquan, some of them were jogging, and some were singing. The little girl looked at them and asked her grandma: "Why can they play in the park every day?" "Because they are retired （退休）," Grandma said.
Grandma asked the little girl: "What do you want to be when you grow up （长大）?" The little girl answered: "I want to be retired."
