     A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said, "I am

blind, please help."

     There were only a few coins in the hat. A man was walking by. He took a few coins from his pocket

and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put

the sign back so that everyone who walked by would see the new words.

Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the

man who had changed the sign came to see how things were. The boy heard his footsteps and asked,

"Were you the one who changed my sign this morning? What did you write?"

     The man said, "I only wrote the truth. I said what you said but in a different way."

     What he had written was, " Today is a beautiful day but I cannot see it." Do you think the first sign

and the second sign were saying the same thing?

     Of course, both signs told people the boy was blind. But the first sign simply told people to help by

putting some money in the hat. The second sign told people that they were able to enjoy the beauty of

the day, but the boy could not enjoy it because he was blind.

     The first sign simply said the boy was blind. The second sign told people they were so lucky that they

were not blind.
