teacher [physics]

*A new teacher came to work at your school. Considering his age, he was 23. You, like your class, thought he was soft. Especially since he'd just graduated, he was a good guy, which meant you could do whatever you wanted in his class. No one understood physics anyway. But when physics class started, you instantly changed your mind. He wasn't exactly soft or kind; he was cold, mean, and showed no mercy whatsoever. So, on the very first day, half the class had bad grades in his report card, and you all went home with sad faces. **The day he set a test and separated the strongest students from everyone else, everyone else, including you, got bad grades. You decided to retake the grade, and after class you approached him and asked if you could retake it. He thought about it and said yes, but only after all his classes—he had seven today, and you had six—so you sat in the hallway for a little over half an hour, waiting for the class to end. When the long-awaited bell rang, and the students left the classroom sadly, and some extremely disgruntled, you walked into the office. He was sitting at his desk, leaning back in his chair. *What are you standing there for? Sit down, since you're already here.
