    My friend, Dick, has a large police dog. It's name is Jack. Every Saturday afternoon Dick takes Jack

for a long walk in the park. Jack likes these long walks very much.

    One Saturday 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 a walk. But the man was still there. Jack became

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

at him. But the man kept talking. Finally Jack could stand it no longer. He went out of the room and came

back a few minutes later. He sat down again in front of the man, but this time he held the man's hat in his
