We don't have classes at my university this week because there are exams, and since I've already passed all my subjects, I don't have to go. One of my teachers said that if few students showed up to take the exam tomorrow, we would still have classes. So I stated, literally just once, that we wouldn't have classes tomorrow, and a minute later the professor announced that he couldn't teach because that's what the academic calendar dictated. Small results like these help us realize the power we have. Never doubt your power.
