Sam 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 tonight. A policeman helps him get out. Then he tells Sam’s wife, “The old man got lost in the street. He asked me to take him home in the car.”
After the policeman leaves, his wife asks, “Sam, you go to that street every night. How can you get lost?”
“I am not lost. I just don’t want to go home on foot.” Sam answers.
