Now the boy is eating his ice cream. The man says, “I go out for a newspaper.” The man goes out. After the boy eats his ice cream up, he stands up and goes to the door.
“Excuse me. Your father doesn't give the money for the meal and your ice cream,” The waiter stops him and says.
“Father? You are wrong. He isn't my father. I don't know him. I meet him in the street. He says he will give me an ice cream if I come here at 12 o'clock.”
