There was a blind man who was sitting on the sidewalk, with a cap at his feet and a piece of wood that, written in white chalk, said:
"PLEASE HELP ME, I AM BLIND".
A creative advertising man who passed him stopped and looked at a few coins that were in the cap and without asking permission he took the sign, turned it over, took a chalk and wrote another advertisement and put the piece of wood back on blind man's feet and he left.
In the afternoon the creative went back to the blind man who asked for alms, but this time his cap was full of bills and coins
The blind man recognized his steps and asked him if he had been the one who rewrote his poster and, above all, what he had written.
The publicist replied:
"Nothing that is not as true as your ad, but with other words."
He smiled and went on his way.
the blind man never knew it, but his new sign read:

"TODAY IS SPRING, AND I CAN NOT SEE IT"
