BOB is an old man. He likes walking in the street after supper. And he goes home at seven o’clock.
But a car stops at his house one evening. A policeman helps him get out. Then he tells Bob’s wife: “The old man got lost (迷路) in the street. He asked me to take him home in the car.”
After the policeman leaves, his wife asks: “Bob, you go to that street every day. How can you get lost?”
“l am not lost.l am tired and l just don't want to go home on foot."Bob answers.
