Throughout the course of our renovations, just about everything has been uprooted and put someplace it normally isn't. I was putting some books back on a shelf when Robert started brandishing a small, plastic vial.
Robert: Daddy, what's this stuff?
Me: That is Astroglide.
Robert: What's Astroglide for?
Me: It's for keeping things slippery.
Robert: Oh. [pause] You mean, like, for a piston engine?
Me: Yeah, baby.
