Mrs. Brown's grandfather lived with her sister and her husband. Every morning he went for a walk in the park. One morning a police car stopped near Mrs. Brown's house, two policemen helped Mr. Brown to get out. One of them said to Mrs. Brown: "The poor old gentleman lost his way in the park and telephoned to us for help". Mrs. Brown was very surprised, but she thanked the policemen and they left. "Grandfather", she then said, "You go to that park nearly every day. How did you lose your way there?" The old man smiled and said: "I didn't lose my way. I was tired and I didn't want to walk home!"
