I think you have to accept that an artist also has a relationship with his or her art and his or her fans: you are in an open relationship whether you like it or not. Give the artist room to go into the place they create (literally or metaphorically) . And love them when they can't remember where they put their keys.
Neil GaimanI love doing the readings. The readings are the fun bits... The readings are probably the things that actually keep me going on these. If I couldn't do the readings, I wouldn't do the [signing] tours. I get to stand up there and read to a bunch of adults who in many cases nobody's read to in years, since they were about five. They just squat on the floor. That's enormously enjoyable.
