A lot of professors are overworked with classes and programs too. One of my girlfriends uas a professor for anatomy who teaches two full college courses before going to her massage school to teach anatomy. She says you can tell that the professor isn't really there mentally. Sge never actually prepares for the courses she's supposed to be teaching, but you can tell us just from exhaustion. I wonder how many are like that and just forget what coursework they're currently preparing for others.
