In its silence, a book is a challenge: it can't lull you with surging music or deafen you with screeching laugh tracks or fire gunshots in your living room; you have to listen to it in your head. A book won't move your eyes for you the way images on a screen do. It won't do the work for you. To read a story well is to follow it, to act it, to become it - everything short of writing it, in fact. Reading is not 'interactive' with a set of rules or options, as games are; reading is actual collaboration with the writer's mind. No wonder not everybody is up to it.
Ursula K. Le Guin
