You know what my professor does when you enter the class late? He freaks you out. Here is what he does, when you stroll in late w/ your books and bag in your hand. He’ll say, “Nice that you could make it class. You can do the next case.” By the time you get to your seat, flip frantically to the page of the book that the case is in and try to compose yourself and trying to remember what the heck the case is about, the teacher will say, “We are waiting.” You stand up to brief your case trying to summary the case in your mind before talking out loud. Horrible isn’t it? It’s to teach us a lesson, not to be late for class. I haven’t been put through that yet and don’t want to.
Also, when you go to the restroom and come back, he’ll say, “since you’re already up, you can do the next case.” It’s like, “what the heck? I just got back.”
