Once upon a time, a man and a woman had seven foolish sons. The boys lost the family cattle, they broke the plough, and everyone cheated them at the market.

Their mother prayed, “Oh God, why did you send me all these foolish children? Please, send me one more son, and let him be wise.”

In time the woman gave birth to another boy. The child was tiny. “We’ll call him Sinziro,” his mother said.
