The conference organizers must have been really scraping the barrel when they invited Professor Wortschlachter as a keynote speaker. Until you saw the conference programme you’d never heard of him, and from what the handout has to say about him you can see why. You’re subjecting yourself to his lecture through a general sense of obligation (or, at least, fear of appearing less enthusiastic than the other delegates), but your expectations are not high. So far, Wortschlachter has triumphantly fallen short of them.
