D.J. Smith wanted to go to school. When he first had the idea, everyone in his town thought he was crazy."Are you kidding? Go to school at your age?" said one man. "That's right. You are blind without your glasses on," said another person. "Besides, you can't remember things easily now," his wife also said. But nothing could stop old D.J.Smith from going to school. He was born to a poor family. His parents didn't have enough money for him to go to school when he was young. He had to work hard to helo his family. Now he owns the biggest supermarket in the town. D.J.Smith said to his wife," Money means nothing, but knowledge does. I always want to study. But when I was young, I couldn't go to school. But now, money is not a problem." Yesterday was a special day for D.J.Smith. He graduated （毕业）from school. When he took the diploma from Mr Wilson, he couldn't help crying. Everyone there was moved, too. It's never too old to learn. D.J.Smith did it.
