This evening after getting his pajamas on, little man comes out to the living room, obviously pleased with himself, and offers an explanation for his ensemble. He says
I picked out this shirt because it has dinosaurs on it and when I grow up I'm going to be a paleontologist. And if I get fired, I'm going to build airplanes. Not paper ones but ones made out of metal so you and Papa can fly in them. Yep.
And with that, he marched out of the room.
