We would love to just draw a picture explaining this whole theme, but that would kind of defeat the whole purpose of literature. It's about words. And words, well, not everyone understands them. Take Mau and Daphne, for instance. Nation's two protagonists don't speak the same language—and Mau even misunderstands the pictures Daphne draws at first. But instead of going crazy and trying to shoot each other (okay, Daphne tries to shoot Mau that once, but she feels really bad about it later), they patiently work it out. By doing so, they come to a greater understanding about each other, each other's culture, and the world.
