" The most important things aren’t always in the main story; sometimes the real meaning is scribbled in the margins. You know, when you pick up a secondhand book and people have written stuff in it. Um, read what other people think is important. Maybe they underline a sentence or just a word. Sometimes it has nothing to do with the story but how they feel at the time. "
