The knowledge that I have a manuscript coming to read and comment on.

Also, that the chimney sweep that I made an appointment with three years ago called this morning to set a time to arrive, just when I was thinking that the chimney probably needed cleaning. ("Peter, dear, the sweep's come!")

Also, I now have a pretty-much-complete set of Tamora Pierce's books. Plus four dupes, because I thought that one shipment was complete when it wasn't, so I double-ordered, but never mind that.
