When we were discussing Rosencrantz and Guildenstern, we talked about how the novel follows what happens when, in Hamlet, Rosencrantz and Guildenstern are "offstage". Ms. Quinet commented that you would expect Rosencrantz and Guildenstern to be doing something more interesting when they're offstage than flipping a coin like fifty times.
I thought that this observation was interesting because it implies that characters have a life outside of the lines that have been written about them. This idea brought to my mind a scene in The Fault in our Stars when Hazel Grace, the main character, meets the author of her favorite book. She asks him about what happens to the characters when the book ends, and he responds that they are just characters and that they do, in fact, not exist outside of the book. It's a bit of a disheartening scene because as readers we like to imagine that our favorite characters really do exist and that they live just like us.
