The Wise Son In Africa, in the county of Ghana, there once lived a man who
had three sons. One day, before he left on a long journey, Kofi
gathered his sons around him. He gave each child an egg. "I will be
gone for a long time," he told his sons. "Use these eggs to help your
mother."
But as soon as Kofi left, the two older boys cooked and ate their
eggs. The youngest boy, Ebo gave his egg to his mother who put it
under a hen to hatch.
