Eyesight to the blind
One day, a blind boy was sitting and waiting for someone to drop a coin so he could buy some food.
He had a blackboard beside him with a crookedly written note:
"I'm blind, please feel pity."
Suddenly, a man approaching him dropped a coin and erased what was written on the board.
The boy realized it but ignored it. Then, he heard a lot of coins were being dropped in his can. After an hour, the man came back and saw how he was doing.
The boy said: "My can is full of coins now, what did you write on my board?"
The man read it and said, "Today is a beautiful day but I can't see it."
