I can't sleep. My mom is getting an angioplasty in six hours, and I'm skipping my Brain and Human Behavior quiz to go with her. I keep going over the material I'm not going to be quizzed on, as if I needed to know it. What I need, though, is sleep. I need my mother not to need the angioplasty tomorrow. I need to go to school tomorrow and take the quiz. I need my sister to not yell at me over the phone at three in the morning from across the country to make sure my mother will be treated by the best cardiologist the state has to offer, but I'm not going to get that. So instead I sit here and I memorize, and I have the twelve cranial nerves and their functions down.
