A short shameful confession: I once gave Peter S. Beagle a silver origami unicorn at a comicon.
I didn't introduce myself at his booth, though, but rather pounced-and-escaped as he passed by my table in the author alley. I am, in person, as shy as Teri, though I cope differently. I spent more time folding paper, that con, than I did selling books.
(I'm assuming you all have, in fact, read The Last Unicorn and so know why this is a big deal. If you haven't, why are you wasting time on SOL instead of rectifying this crucial omission from your life experience already? Like, RIGHT FUCKING NOW?)
