They boy recognized 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?

The second sign told people that they were able to enjoy 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. There are at least two lessons we can learn from this simple story.The first is: Be thankful for what you have.
