Perhaps you were up till 3am studying for a test in a different class. Or maybe you had a dinner with friends that ran late into the night. Either way, you're tired today, and you've made the mistake of yawning in one of Professor Talbert's lectures.
Well, you should have yawned quietly because Professor Talbert heard your "overly-loud yawn" and he is having none of it! Also, if you want to anonymously tell on the person who yawned, that will be just fine.
