When I was in college, headed for my BA, I had a microbiology class and "aced" the final. When I received my letter grade, the idiot teacher gave me a B+ for the semester. I was pissed. I confronted him and told him for the last 6 years, every grade I received was a 4.0 (A) and this lower grade was really bruising my ego. He admitted that I aced his class, but he has never given out an A to anyone, because in order to reach that letter grade, meant to him that the student was smarter than he was. He was such an arrogant bastard, and my only reply t him was, "I hope I never catch you driving in my city!"
