I want to let your other readers know that even if signing is work for you, you don't let on during. Even when there are far more people than expected, you spend so much time, and are so gracious with each of us, and add those little custom touches for each different book with colored pens -- I use you as an example, along with Stephen Hickman, as to how Big Name Award Winners in sf/f are just as nice to their fans as can be. So no one should feel as though they might get glared at by Neil just for bringing books to be signed.
Not at all. I don't glare. Well, I
can glare (I pride myself on having an excellent glare), but never at people at signings.
