I will answer that question: yes. I even once acknowledged that fact in passing in a blog post, and later supplied a urine wheel. Now Mary Beard has written an entire post on the subject of scholars and their pee. Along the way, she has somehow made loos at Cambridge University relevant to the waste systems of the ancient Romans.
Why do I bring all this up? Last Saturday I was watching the animated film Grave of the Fireflies with Kid #1. When the main character announces "I have to pee," my son enthusiastically declared "YES!" When I shot him my trademark quizzical look, he explained "I've been waiting my whole life for someone in a book or a movie to use the bathroom." After ten years, the wait was over.
By the way, if you are looking for an unremitingly grim film that will leave a dark cloud hovering about you for several days, watch this one. The inability of the boy and girl to give up hope even as their fate becomes increasingly evident to them is as beautiful as it is wrenching.
