Here I sit, writing my next column, "Pax Americana," and these two frat boys are standing behind me discussing how to make a PowerPoint presentation. Argh! I know this isn't a library, but damn it! People are trying to get work done! (Okay, maybe what I'm doing qualifies more as recreation than work, but it's important to me, and I'd like to be able to work on it in peace.) Jerks.
