It was Wednesday night and both me and my suitemate Lauren were up late working on homework. We were each in our own rooms working but her door has a full length mirror hanging on it and just happened to be ajar at just the right angle for us to see each other in the reflection.
I have always been fascinated by reflections, probably more than I should be. I have always been easily distracted from things I’m working on, definitely more than I should be. Lauren and I started chatting with each other, making eye contact through the mirror, and making silly faces at each other. Pretty soon we started mimicking each others expressions and movements and then we started trying to figure out whether we were making the same motions as each other or opposite, based on the angle of the mirror. Homework was not nearly so important as figuring out how the refraction of light works.
