I've always been good at math. It's straightforward, black-and-white, right and wrong. Equations. Da thought of people as books to be read, but I've always thought of them more as formulas—full of variables, but always the sum of their parts. That's what their noise is, really: all of a person's components layered messily over one another. Thought and feeling and memory and all of it unorganized, until a person dies. Then it all gets compiled, straightened out into this linear thing, and you see exactly what the various parts add up to. What they equal.
