     Almost everyone likes dogs, and almost everyone likes to read stories about dogs.

     I have a friend. He has a large police dog named Jack. Police dogs are very clever. Every Sunday

afternoon my friend takes Jack for a long walk in the park. Jack likes these long walks very much.

     One Sunday afternoon a young man came to visit my friend. He stayed a long time. He talked and

talked. Soon it was time for my friend to take Jack for his walk. But the visitor still stayed. Jack became

very worried. He walked around the room several times and then sat down in front of the visitor and

looked at him. But the visitor paid no attention to Jack. He went on talking. At last Jack got angry. He

went out of the room and came back a few minutes later. He sat down again in front of the visitor, but

this time he took the visitor's hat in his mouth. The visitor saw it and was surprised. He laughed and left.
