There was an old man who was always in the same children's leisure square selling balloons.
He was a great salesperson, of course, his family depended on him ...
Every day on arrival at the square, he would let out a few balloons to the wind, this way, attracting his little customers.
Once there was a boy sitting down on one of the benches, watching this man and the balloons.
His favorite one was the red balloon, but the man let the yellow fly, then the white, the green, but did not let go of the red ...
The boy was watching each one of them flying in the sky, but one thing bothered him, the man would not release the red balloon.
Then approached the seller and asked him:
"- Sir, if you loose the red balloon, would it rise as much as others?"
The old man smiled understandingly, broke the line that was holding the red balloon and as it rose in the air, he said:
"- It's not the color, son, is what's inside that makes it rise. "
