For senior seminar, I have to go to an assigned professor to help with my paper and group presentation. I've been going to his office during his office hours, and he was never there. I told my seminar professor and later, the assigned professor emailed me "I'm only in my office when I'm supposed to be there" What is the point of having office hours, which shows when he's supposed to be there, if you're not going to be there, when you say you would be?
