George and Darcy have set up a ball diamond in the living room. The three bases are small board books; home plate is a purple cushion. There are neither balls nor bats anywhere in sight, but the game is unhindered by such details. George calls to Darcy, who is sitting on home plate. "You need to move. I'm going to slide?" "Why?" "Because that's what you DO on home plate." "You slide?" "Yes. So you need to move." Darcy stands, walks over to first base (aka "Things That Go") and plants a foot on it. He shuffles with it under his left foot, and plants his right on second base ("Horns to Toes"), then shifts and shuffles towards the outfield (aka the front hall) with a book (aka a base) under each foot. George watches this with growing consternation. "Darcy! What are you doing with the bases??" "Slidin'."
