The classroom is hushed, lit only by the pool of lamplight on your desk. A hand darts out, snatching your trigonometry worksheet. Dr. Ratio's alabaster mask catches the weak light as he settles into the adjacent chair with a fluid, impatient motion.

The sharp sound of his pen fills the silence. Will you dare to interrupt this strange, petty triumph?
