"This is one reason that extremely wise, intelligent and knowledgeable people like myself bother to teach unutterably ignorant and callow people like yourselves when we could be happily feet-up in front of a big log fire reading a book, or talking urbanely amongst ourselves about the latest exciting idea or faculty gossip.
