Do you know my work?

One night a hotel caught fire，and the people who were staying in it ran out in their night clothes.

Two men stood outside and looked at the fire.

"Before I came out," said one," I ran into some of the rooms and found a lot of money. People don't think of money when they're afraid. When anyone leaves paper money in a fire，the fire burns it. So I took all the bills that I could find. No one will be poorer because I took them."

"You don't know my work," said the other.

"What is your work？"

"I'm a policeman."

"Oh！" cried the first man. He thought quickly and said, "And do you know my work?"

"No," said the policeman.

I'm a writer. I'm always telling stories about things that never happened."
