It's two o'clock in the afternoon. The sun is shining and it's very hot. Now she's walking in the street. There are no trees and she's fat, so she feels very hot. But she doesn't notice that a boy is walking behind her. Then she meets a friend and says hello to him. Her friend asks her, "Who's the boy behind you?" Now she sees the boy. She also asks, "Why are you walking behind me, boy?" "There is no shade in the street, you know, "answers the boy. "It's cool behind you, I think."
