Billy heard on the radio that a monkey escaped from the zoo. When he woke up the next morning he saw the monkey in his room. He wanted to keep it secret from everybody and to have the little monkey there forever. His little sister came to his room unexpectedly and saw the monkey. She started crying and when their father entered Billy's room and saw what it was about, he decided to take the monkey back to the zoo. Billy was very sad, but his father told him that they would visit the monkey every Sunday.
