I have an almost holy reverance for libraries. I give dirty looks to people in the library who make noise. Why, just yesterday I was in the new arrivals section when two people were behind me making all kinds of ruckus in the DVD aisle. They probably didn't notice my intimidating 4'11" frame but I enjoyed giving them dirty looks anyway. They quieted down and I decided we didn't need to throw down. It was my pleasure. I'm pretty sure I could've taken them.
