We used to have a player who would read a magazine or "The DaVinci Code" when it wasn't actively her turn. As such, we would then have to point out which figures were enemies and which ones weren't, redescribe all the actions taken since her last action, at which point she would ask us what she should do, we would list options for her, she'd want us to pick one, we'd try to encourage her to actually play her character, she would almost always opt for firing the crossbow (you've guessed she's playing a cleric of Pelor at this point, right?), we would then have to tell her which dice to roll, and then she would go back to reading and paying no attention to the game.
Notice use of the past tense in my first sentence.
