Hm, I've actually met one person that I really really admire - this was back in 2013 at the first Image Expo. Brian K Vaughan was just sitting at his table staring off into the distance. There weren't many people at this con (probably why they moved to a much smaller venue in subsequent years), so not many people were stopping by his table (which is crazy because it's BRIAN K VAUGHAN!). This was a little while before SAGA had come out.
I got a rare chance to talk to him for about half an hour while he signed some books. We actually didn't really talk much about comics at all - he ended up giving me a ton of life and relationship advice. Our conversations were all about the background noise that occurs behind the scenes while we write, all the small things that creep into our writing. At the end of our conversation, I blurted out "I want to be just like you when I grow up!"
He paused midway through a signature and slowly looked up at me and replied, "You want to be bald?"
And that was that.
Hm, I would also really love to meet Karen Berger one day. I attribute most of my love for comics to her, although I guess, I have no idea what I'd say to her.
