You call one of your graduate student friends who you think is a good choice to take over the class for you today. She says she has time and would be more than happy to help you. Since you have prepared the lecture so meticulously, you are able to precisely tell her what you want her to do before, during, and after the class. Then, you email her your syllabus, lecture, presentation, and all other necessary documents. Next, you contact the instructor of the course explaining your absence and your strategy for today’s discussion session. After class, you contact your friend, thank her profusely and ask her how the class was and if there is anything you should know before your next session. Then, you go back to bed to get well before the next discussion session.
Scenario 1: Don't worry! You can handle this.
