Today is a Spring Day

  A blind man was begging in a city park. Someone approached and asked him whether people were giving generously. The blind man shook a nearly empty tin.

His visitor said to him, "Let me write something on your card." The blind man agreed. That evening the visitor returned. "Well, how were things today?"

The blind man showed him a tin full of money and asked, "What on earth did you write on that card?"

"Oh," said the other, "I merely wrote 'Today is a spring day, and I am blind.'"
