Last Tuesday, I had been looking for a book to add to an Amazon.com order to qualify for free shipping, and couldn’t think of one I especially wanted. That same day, completely independently, I had gone to a bookstore to look for a particular book I wanted to buy, which they didn’t have. Strangely, these thoughts did not intersect until just now.

I’ve already placed the order, of course, and I also still want the other book. So now I need to come up with something else to buy for this order…
