I didn't kill her. But I wanted to. Just like I want to kill anyone who says that to me. I do something for my job seven days a week. I absolutely spend hours every day of the semester working on my job, grading, reading, preparing, dealing with students.
Even during winter and summer breaks I work on this, writing, publishing, updating courses with new books, assignments, etc.
Yet, I've never met a layperson who didn't think I was just a lazy motherfucker who worked two days a week.
