　　Lillian Beard whistled and smiled while she worked. “Why are you so happy?”her co-workers asked her.

　　“Last week I got my income tax refund,”Lillian answered.“This morning I went to the bank and cashed the check. I have $ 462 in my pocket. I’m thinking about the money. How will I spend it?”

　　After work, Lillian came home and decided to wash come clothes. She looked at the jeans she was wearing. They were dirty, so they put them in the washing machine, too. Ten minutes later she thought, “The money! It’s in the pocket of my jeans!”Lillian ran to the washing machine and took out the jeans. The money was still in the pocket, but it was wet. Lillian put the money on the kitchen table.

　　A few hours later the money was still wet. “Hmmm,”Lillian thought.“How can I dry this money?”Then Lillian had an idea. She could dry the money in her microwave oven! Lillian put the money in the microwave, set the timer for five minutes, and left the kitchen.

　　When Lillian came back a few minutes later, she saw a fire in the microwave. She opened the oven door, blew out the fire, and looked at her money. The money was burned.

　　The next day Lillian took the burned money to the bank. A teller at the bank told her, “If I can see the numbers on the burned bills, I can give new money.”Unfortunately, the teller found numbers on only a few bills. The teller took those bills and gave Lillian $ 17.

　　A newspaper reporter heard about the burned money. He wrote a story about Lillian for the newspaper. Several people read the story and called the newspaper. “Tell Mr. Beard to send the burned money to the US Department of Treasury,”the people said. “Maybe she can get her money back.”

　　Every year about 30,000 people send damaged money to the Treasury Department. Experts there look carefully at the damaged money. Sometimes they can give people new money for the damaged money. Once a farmer’s cow ate-his money ––– thousands of dollars. The farmer killed the cow and sent the cow’s stomach, with the money inside, to the Treasury Department. The experts gave the farmer new money.

　　Lillian sent her money to the Treasury Department. The experts looked at Lillian’s burned money and sent her a check for $ 231. What did Lillian buy with the money? She didn’t buy anything. She gave the $ 231 to friends who needed money. Lillian said, “When I burned the $ 462, I thought, ‘Well, my money is gone.’”The check for $ 231 was a big surprise. I decided to give the money to my friends. Money is important, but people are more important to me.
