There once lived an old man in a nice house. Behind the house there was a big garden. He planted many plants there. He took care of his flowers all the time, watering and fertilizing（施肥） them.

    One day a young man went by the garden. He looked at the beautiful flowers, imagining how happy he could be if he lived in such a beautiful place. Then, suddenly he found the old gardener was blind（瞎）. He was very    about this and asked, "You can't see these flowers. Why are you busy taking care of them every day?"

    The old man smiled and said, "I can tell you some reasons. First, I was a gardener when I was young, and I really like this job. Second, although I can't see these flowers, I can touch them. Third, I can smell the sweetness of them. As to the last one, that's you."

    "Me? But you don't know me," said the young man.

    "Yeah, it's true that I don't know you. But I know that flowers are angels（天使）that everybody knows. We enjoy the happiness these flowers have brought us."

    The blind man's work opened our eyes and pleased our heart, which also made his life happier. It was just like Beethoven, who became deaf in his later life and wrote many great musical words. Beethoven himself couldn't hear his wonderful music, but his music has encouraged millions of people to face their difficulties bravely. Isn't it one kind of happiness?
