The mother and her daughter were washing the dishes in the kitchen, while the father sat with his little boy Jamil, seven years old, in the sitting room, leafing through some magazines. Suddenly they heard a clatter, followed by the smashing of dishes. Father and son listened, waiting for what would follow that storm. Silence reigned; so the boy remarked: "It's Mama."

His father asked him: "How did you know that?"

Because if it had been my sister who broke the dishes, Mama's voice would have been raised in a funeral oration!
