Mr. and Mrs. Clarke were going to America for their holidays. They had a dog called Billy. They liked him very much. But they couldn’t take him to America with them. So they found a place to leave him while they were away. At the end of their holidays they got back to England very late at night so they didn’t go to get Billy. The next morning Mr. Clarke got into his car and drove happily to get Billy. When he got home with the dog he said to his wife, “Dear, I don’t think Billy has enjoyed his days at that place. He made lots of noise all the way home. I guess he must want to tell me something!” Mrs. Clarke looked at the dog carefully and answered, “ You are quite right, dear, but he wasn’t trying to tell you he hadn’t enjoyed his day at that place. He was trying to tell you that you had brought the wrong dog home. That isn’t our Billy.”
