Addendum.

The next night, when I ran into the Catalan guy and his one Spanish friend who studies Don Quixote (they're inveterate barflies), his one Spanish friend was looking tired, and when asked why, he said he had been at a lit conference and given a paper on the interruption in Don Quixote.

"I did not realize that Don Quixote was not finished," the Catalan quickly said, and his friend looked perturbed for a second, and then hit him.
