Klara and Paul share a moment of concern and consideration regarding her ability to learn Josie's heart, which he describes as: "Rooms within rooms within rooms . . . No matter how long you wandered through those rooms, wouldn't there always be others you'd not yet entered?" (216). What do you make of Klara's response about the finitude of such metaphorical rooms? Would you say, in your own experience, you've been able to explore and learn all the rooms of your own heart, or another person's?
