Until I meet any obviously fake human beings — and I think they’d have to be held together with glue, or have the eyes painted on, or really be dolls or slugs or something — I think all people, not to mention fans, nerds, geeks and suchlike are real.
Some people haven’t read/seen/done as much as others. Some people haven’t been around as long. Some people wear T-shirts without knowing everything about what the T-shirt represents. But they are still real, and (and this is the important bit) everybody starts somewhere.
People at my signings sometimes tell me, apologetically, that they aren’t real fans, they’ve only read one book or a single comic, not like the people who know every obscure reference I make and win quizzes on my life and times that I would probably fail. And I tell them I’m glad they read the book. And I am.
