John woke up in the middle of the night and saw something white【21】his garden. It seemed【22】towards the house.
"That【23】a thief !" he thought, and he took his gun and shot【24】him. Then he went back to bed,【25】he was too frightened【26】of the house in the dark.
The next morning John went out and saw one【27】his white shirts hanging【28】the clothes line in the garden. His wife【29】washed it the day before and【30】it out to dry. Now it had a bullet hole right through the middle of it.
"My God," said John, "I was lucky last night. If I had been wearing that shirt, the bullet would have killed me!"
