Craig Newmark notes that faculty at Wharton are now being more the stickler about students coming to class and behaving decorously. You mean, when you are in a meeting with your boss you can just get up and go potty whenever you want? I tell my students on the first day of the guy that hired me, who would tell his classes about the woman who broke her leg the night before the final exam and couldn't come up to the third-floor classroom to take the final. Could she have a make-up test? No, he said, that's not permitted in the syllabus. The young co-ed was carried into the classroom by a male friend; upon completion of the exam, she whistled and he came and took her away. In twenty years I have not had a similar story to tell, but not for lack of trying.
