Being a professor at a university like Cornell must be really hard. You get all those stressful summer vacations, which you can use to write your next novel. There’s also the looming threat of tenure, which ensures you that, short of dying or murdering a student, you will be guaranteed your job forever. Gosh, maybe that’s what this particular professor was thinking about when he lost his shit over a student yawning in his classroom. He thought about his life as a revered professor and just got very upset.
