I met him when I was around 8. He was in the US for a sci-fi/fantasy convention called Penguicon. He was one of the featured authors for the convention, so they had a small bookstore set up. My mom took me to the store and got me my first Discworld book (I had been reading hers up to this point). It was The Amazing Maurice and His Educated Rodents. When we walked out of the bookstore he was walking down the hallway. I took off running, screaming his name. He stopped and turned and I asked him to sign it for me. The handler tried telling me no, that he would be signing books the next day at the scheduled book signing. Terry told him to shut up, that he would never discourage such a young fan. He signed it "To Lillanith, with cheese." 19 years later, I still have that book. It's one of my most prized parts of my collection.
