I spent a lot of time as a volunteer in a nursing home in Amherstlast summer. I was reading Dante’s Divine Comedy to an old man, Mr. Shulman. One day, I asked him where he was from. He said, ‘Just east of here, the Rockies.’ I said, ‘Mr. Shulman, the Rockies are west of here.’ He did a voilà with his hands, and then said, ‘I move mountains.’ That stuck with me. Fiction either moves mountains or it’s boring; it moves mountains or it sits on its ass.
