There is an African folktale about a mouse who pulls a thorn from the lion's paw. The moral of the story is twofold: first, that it takes courage to face a creature that can ultimately destroy you; and, that even the smallest and weakest can be of great use to the greater and stronger.
I often wonder if the lions of the world ever take stock in this story. They wander through life exercising their power, throwing their weight around as if they are invincible. Do they realize that a tiny, seemingly insignificant thing could easily bring them to their knees? No, they are too narcissistic to comprehend that their reign is limited and when they are afflicted with the equivalent of a thorn, they had better hope that a courageous and compassionate little mouse is around to help.
