An ancient Greek parable tells of a cat that was magically transformed into a Princess. The Princess was elegant, well mannered, and always with a ready smile on her face. Everyone seemed to be enchanted by her nobility.
And then, one day, as the Princess greeted a group of admirers, a mouse happened to run into the room. In an instant, the Princess was transformed back into cat-like behavior. The illusion was over. Everyone realized she was not really a Princess after all, but was a cat who was posing as a Princess.
