A certain amount of obliviousness was a necessity for anyone proctoring study hall, given that the job required them to continuously overlook the hordes of students not studying. As I knew from personal experience, this particular teacher didn't even notice when, for example, you passed out on your physics book. A just-barely-tardy wasn't going to rank much higher on the notice meter. Feeling vaguely wicked for getting away with something that at least two of my teachers considered a cardinal sin, I pulled out one of my textbooks and offered my appreciation to the proctor by at least pretending to study. I flipped through the pages, looking at the pictures, and with each one, I traced my finger over its surface, thinking how the contrast between photos taken in the seventies and the modern world was in some way similar to the differences between the Other-world and Earth. It wasn't just a difference in color, and it wasn't just a difference in sheer size. It was a difference so great that the two didn't even occupy the same number of spatial dimensions.
