So I've figured out how to follow myself

I'm currently enrolled in a Calculus class, and a TA substituted for my regular teacher a few weeks ago. That particular day was a lab, so we usually just ask questions on the homework throughout the hour. Well this man, Brian, is a very happy person who loves math: a dangerous combination. He energetically conducted the class, pausing part way through to explain some of his graduate work about the shape of the universe. He then went into greater detail about some various possible shapes, ending by explaining that in one universe you can reach up and grab your own ankle. (Maybe I'll explain it some other time.)

So, figuring out how to follow myself seems a similar feat.
