Unseen Academicals

Yesterday I proved my theory that the only way not to spend money is not to leave the house. I went out for non-book-buying purposes and nevertheless came back with a copy of Terry Pratchett's Unseen Academicals. I'd been resisting so nobly, and waiting for it to become available at my library! But I was 52nd in the library's queue, which has not moved at all in two weeks, and my patience finally surrendered to the urge to read it now.

So. Bought it, read it. It made me sad.
