(EASY QUESTION) A pregnant woman wants her child to have very good manners. Every night while she's going to bed she rubs her stomach and says, "Be kind, be kind."

Nine months comes and goes and she doesn't have the baby. She refuses to have doctors look at her because it is against her believes. She dies at the age of 70 and still hasn't given birth. What is the explanation?

The mystery is solved when doctors inspect her. Inside of her womb they find two little men saying to each other "No brother, after you."
