The Dance Sign

At the blue end of the blind alley the sign said: DANGER! The letters were painted big and bold in red, on a black surface. One day a small man, dressed in green, stopped at the sign. And then from his yellow toolbox he pulled out a white airbrush and began to spray with black paint the sign board, until it erased the letter R in red. Next, he targeted the letter G. However, he sprayed black color only on part of the red G, turning it into a letter C. So now the sign read in red on black: DANCE! Then the small man, dressed in green, put back the white airbrush into his yellow toolbox and he quietly left the scene. A few days went by and nothing much happened. But then by and by more and more people came to see the new sign in red on a black background that said: DANCE! And many of them, men and women, some old, some young, followed the instruction and they began to dance. And in the end at this blue end of the blind alley a jolly music band also appeared and it played wonderful crowd pleasing popular pieces from the morning till the small hours of the night.
