Today I was a high school social studies teacher. They watched Cinderella Man in US History and Crash (with TV edits) for Current Issues. These are both great movies that I would never have watched otherwise. Being a sub is sometimes really really easy and sometimes the kind of nightmare that makes you wish you were asleep just so you could wake up. Today was easy, but I needed 2 shots of espresso and 16 oz of coffee to stay awake. For me the balance is not so much about how to handle the class, but how to pace my infant-hamster-sized bladder.
