Sally's old grandfather lived with her. Every
morning he went for a walk in the park and came home at half past twelve for
his lunch. But one morning a police car stopped near Sally's house at twelve o'clock,
and two policemen helped her grand- father to get out. One of them said to
Sally, "The old man lost his way(迷路) in the park
and called us for help, so we sent a car to bring him home." Sally was
very surprised (惊讶), but she thanked the policemen and they left. "But,
grandfather," she asked, "you go to the park every day for twenty
years. How did you lose your way (迷路) ?" The
old man smiled and said, "I didn't lose my way. I was just tired and didn't
want to walk home."
