The smell of a library -- or of lots of books in one place, really -- is one of my all-time favorites. It's like inhaling microscopic bits of Mind. For you, now, let me see...how about: School, Promises, Trains, Labyrinths, Siblings, Vegetables, and Writing (how could I not include that one??). Interpret them how you will, and take what time you need (I think it took me about five days to get mine done!).
