Once upon a time there was a little boy, his father, made him some wings outta feathers and wax. He told the young man not ta, fly to close to the sun, or else the wax would melt, but, the young man in his arrogance, ignored the warnings of his father, and he flew too close to the sun. The wax melted and he fell to his death.
