Linda loves her dog Davy. They went to New York City last Saturday. While Linda was buying a newspaper at the train station, the dog got out of his box and ran away. The station was crowded and Linda couldn’t see Davy anywhere. When Linda shouted his name, some people looked at her but Davy didn’t come. Then she called the police. While she was talking on the telephone, Davy met another dog outside the station. While the police were coming, Linda walked around the station and called Davy’s name. She didn’t think about looking outside the station. Finally, a little boy said to her, “Did you look outside? I saw a big black dog when I came in.” When Linda finally saw Davy, he was jumping and running with another dog. There was a police officer next to them. The police officer said to Linda, “I think my dog found your dog.”
