I was fortunate enough to meet Terry Pratchett when he was in S. Africa in '92 or '93. I stood in a queue that went almost clean around the mall, for more than an hour, with a pile of books in my arms, along with a group of absurdly young people.
During that long wait, as the queue inched forward, I rehearsed what I would say when I finally met him. But when the moment arrived and I plonked the pile of books on the table, the only words out of my mouth were, "I just love your books."
He smiled but the look on his face said, 'is that the most original line you could come up with?' But he signed all my books!!! Even if he thinks I'm the biggest dork ever, those books are the first thing I'd grab if my house ever caught fire.
It's sad that he's not well.
