Someone in the office I work in is leaving in a couple weeks and his co-workers wanted to buy him a parting gift. He's a fan of science fiction and likes apocalyptic literature in particular. A fellow co-worker who knows I write and thinks highly of my writing suggested a short story I'd written that was published in an anthology of apocalyptic stories. They ordered a copy of that anthology on Amazon for him. What's really amazing is, they actually asked me to autograph it for him!
They actually thought I was bestowing an honor on them by agreeing to autograph it. In truth, the honor was mine. This is what all us writers live for - recognition from fans. There is no greater feeling than to hold a book in your hands that you have written in part and have someone ask you to autograph it for them. Okay, it was only a minor publiscation and I only got $20 for the sale, but the exposure is easily worth ten times that.
