I enjoy those small chats you have when people come up and talk to you about your work. It only involves a few seconds of effort to be nice to those people, and I am very grateful for the kind words that people have taken the trouble to express to me in person.
People tell me they laughed hard enough to wake their spouses, that they've given away numerous copies to friends, and that it's the one Trek book they'll give to people they wouldn't expect to like others.
