Amazingly, not everyone on Earth is reading Curious George or Eric Carle to their kids—Koreans have their own set of classic children’s books, about which I naturally know nothing at all. But yesterday after two hours of tutoring my wife, A., came back home with a couple of hard slim volumes for our son, who alternately loves and despises works of fiction, much like his father—he devours them and slaps them as hard as he can, while I devour them and also devour myself, convinced I can never hope to reach such levels of mastery.
