Thank you, everyone, for making me feel welcome.
You might have some luck if you contact Terry's agent, Colin Smythe.
If he can't answer your question, he may be able to point you in the right direction.
Welcome to the site!
I sent Mr. Smythe an email first, as he has been very helpful in the past, but no response this time. He may have finally gotten tired of dealing with me--he has been SO sweet and helpful!
Jan Van Quirm, thank you for your advice. It was just a couple of sentences buried in a piece about something else, so it is very hard to find. I only know that it was text, not audio, though it could certainly have been a transcript of an interview (likely, even). I found it originally while doing research either on Google or through the GSU library search engine. Such a needle in a haystack!
That said, if anyone wanted to share an "Aha!" moment from Discworld...something that really made you sit up and take notice of something within yourself or your fellow man, I would love to hear it. I love when Tiffany wants EVIDENCE that witches are wicked, and notes that while the fairy stories are not real, what happens because of them is; I also just about got shivers from the dragon pointing out that what he is is the direct result of the evil in the human mind.
