Abacus: "Mama, when are we going to have the sex talk?"
Me: "Um. Do we need to have the sex talk? Do you have questions about something?"
Abacus: "Well, I think I know what the sex talk is. It's like talking about where babies come from."
Me: "Actually, you have a pretty good idea of where babies come from. It's more about how babies are made."
Abacus: "Okay, I'll let you know when I'm ready for that talk."
