A child's unintentionally revolting mind

I hear people talk about the unknowingly magical minds of children all the time, mainly on television. For these people, I would like to present a conversation I had with the six-year-old boy I babysit. We were sitting on his bedroom floor, playing the card game War.

Him: I want to have sex with my mom.

Me: ... Oh. Well...

Him: Sex is when you have a little meal in bed with your wife or girlfriend.

Me: Oh!

Him: I want to do that with my mom.

Me: Well, that sounds like fun.

Him: Have you ever done that?

Me: No. Never.
