Adultery

Chris: ::to me, in front of the children:: My back is feeling so painful that I would even prefer a backrub to... "long-haired carpet"-ing.
Me: ::blink blink:: Oh! ::laugh::
Daniel: What? I don't get it.
Me: Yeah, you're not supposed to. Daddy was talking in grown-up language. Actually, Daddy was talking "adult" language.
Daniel: What?
Chris: Don't worry about it, you'll get it when you're a teenager.
