It's interesting that he doesn't share anything about his life, isn't it? Even if his body is not in the Bay Area he doesn't show any evidence of having been around.
Even Piers Anthony would talk about the random things that happened in his life, but Graham doesn't.
I think he might have downvoted me even for asking :)
Seriously though, I can't really blame him. I got a few days fame back in the day and it was a scary thing to watch a mob of strangers picking on my past and judging. Even people who I thought are my friends acted extremely strange - as if they don't know me personally and joining the mob of haters or lovers.
