“I swear I’m not imaginary.” An uncontrollable grin spread across my face. “I would know if I was imaginary, right?”

“I'd love to write some porn, but I don't know if I have the right engines. When I was a young man and I was tempted to write porn, imaginary parents would appear over my shoulder and read what I was writing; just about the point that I managed to banish the imaginary parents, real children would lean over my shoulder and read what I was writing.”

Because I'm creating an imaginary — it's always imaginary — world in which I would like to live.(Interview, The Paris Review)”
