A blind man took out a small blackboard and put it near him. There was a sentence on the blackboard. It said. "I'm blind. Please help me." Some people walked by and gave him some coins. When the coins touched the ground, they made a little noise. And the blind man nodded(点头) his head and said "Thank you." Then a young woman came up to him. She cleaned the words on the man's blackboard and wrote a new sentence. Guess what? Many people gave the blind man more coins. And the coins made much more noise. He had no time to nod his head and say thank you.
At last, the woman came back. She stood in front of the blind man without a word. The man knew it was her. He asked, "What did you write on my blackboard?" The woman smiled and said, "I did nothing, but just made your words beautiful." It said, "It's a beautiful world, but I can't see it!"
