(TROOF STATUS: irrelevant details like names all wildly different changed. All else preserved)
Back when I was in college, there was a girl, let us call her Alice, who was in my circle of geeky friends. She played magic and the Star Wars CCG, she made calculus jokes, all the good stuff. Also she had a very dirty mouth and talked up a good session in bed, in mixed company. By October, Alice was dating Bob. By November, they weren't. By December, Alice was dating Charlie. And then we get to the end of term.
