At Dave Eggers’s suggestion, we’re starting the interview by life drawing together. The novelist dropped out of art school but has been drawing for decades, and his new book is set in the art world. Prudence, our model, stands before us with her palms open, nude but for a pair of black knee-high socks. This, unsurprisingly, is an interview first for me. Eggers shows me how to hold my pencil at arm’s length and use my thumb to measure Prudence’s proportions.
