I taught for a semester at a local community college. I was teaching two classes, one in the morning and the other in the early afternoon. Then this other part-timer left his class in a huff because the department head reminded him in a letter that he had to keep office hours. Like an idiot, I agreed to take over his class, which was a night class, which meant that I was so tired because my home wasn't close enough for me to go home and take a nap since I had to get up early in the morning for the one class, and had to stay very late for the other class. Ugh! At least I made more money.
