Prostitutes

Mama and her little daughter are driven home by taxi. They have to drive through a district in which women walk the streets. The small girl asks: "Mama, what about the girls who are standing in the street and looking at us? What are they doing?"
The girl's mother says: "These are women who are waiting that they are picked up by their husbands in order to get home from working in their office!"
Suddenly, the taxi driver says: "Why don’t you tell your daughter the truth? These are women that go to bed with men for money!"
"I see!" says the little girl. "And what about the children these women get? What are they doing?"
The girl's mother who is still angry about the taxi driver answers: "They become taxi drivers as soon as they are adults!"
