Once upon a time, there was a painter who was asked to portray Alexander the Great. The great king had a horrible scar on his forehead. the painter did not want to show the scar in his painting. He was afraid that it might bring disgrace to the King's name. But if he removed the scar, his portrait wold not be true.And the King would not be satisfied with such a false work. He spent many nights searching for an answer. Finally he hit on a good idea. It was to draw a picture of Alexander the Great resting with his hand on his hand on his forehead.
