I've heard that Maynard's extremely shy.
I set up an event for him a few years ago. He was extremely polite but not overly talkative. We figured out we'd both lived near each other as kids, and that was kind of goofy. He's super smart, and maybe a little shy. He was really nice to me, and I was just a peon.
My sister got to go back stage and do a meet and greet thing. When my sister asked him for a pic, he turned around and told her and her friend "You can take a picture of my back". Sister said he was a dick and wouldn't let them take a pic(which was the whole point of the meet and greet). He told them "take it or leave it".
