Context: Reading for me was a refuge. I could escape from everything that was miserable in my life and I could be anyone I wanted to be in a story, through a character. It was almost sinful how much I liked it. That's how I felt about it. If my parents knew how much I loved it, I thought they would take it away from me. I think I was also blessed with a very wild imagination because I can remember, when I was at an age before I could read, that I could imagine things that weren't real and whatever my imagination saw is what I actually saw. Some people would say that was psychosis but I prefer to say it was the beginning of a writer's imagination. If I believed that insects had eyes and mouths and noses and could talk, that's what they did. If I thought I could see devils dancing out of the ground, that's what I saw. If I thought lightning had eyes and would follow me and strike me down, that's what would happen. And I think I needed an outlet for all that imagination, so I found it in books.

Variant: When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much the old man had learned in seven years.
