Having been lucky enough to be on the other side of the table; the person who's wares people (fans, peers, etc.) come to get signed & appreciated/etc. (thank you very much), doing public signings CAN be tricky. I'm usually empathetic for the "odd man out," especially since I grew up wondering if I was odd for loving comic books (so much so I made it my career), but having grown up in NYC and trucked around artists all my life, I'm used to personality variables and I've tolerated or navigated many a challenging confrontation to a modicum of success. But, there have been incidents that made me question future signings as certain "fans" become self-entitled to the creation and/or exploit access to the creator. For a guy who was never shy to rip off his t-shirt in public just for the fun of it, I've started to hesitate attending upcoming events, including ones I'm NOT the focus of because of the unsolicited, overt intimacy that the legacy of the work and/or social networking purports to yield. Listen, I know what it feels like to connect to the work, to feel that I connect with the author/s of said work, but I also know there is a socially acceptable line that can only be crossed respectfully once a human connection is brokered.
