Those people that work in a building, but choose to go #2 in a “foreign” bathroom. The political science department is upstairs from us on the 3rd floor and the econ department is here in the second. Every once in a while I notice a stranger coming out of a stall as I am brushing my teeth. I have now seen him 3 or 4 times … and learned that he works upstairs (maybe a student, maybe a teacher, I’m not saying).
Back to grading! And yes, expect a post on that shortly.
