It takes one durable person to believe that fantasy is as potent as reality. Seeing too far into others’ lives can make you cynical. Novelists face danger, spending their lives imagining adult temptation and corruptibility. Holding on to the great “What if?” requires a willingness to live wide-eyed. A readiness—even an eagerness—to go on being surprised. When I’m writing from a child’s point of view, I sometimes find it helpful to literally get down on my knees and walk around the house. I’m once again a creature four feet tall. You can see the undersides of tables. Electrical outlets near the baseboards become fascinating again.
