One day, when my oldest children were toddlers, I found myself reading a novel, sitting in a rocker I’d pulled into the kitchen beside the fridge. When one of the children fussed for my attention, I’d open the fridge door and toss a snack to keep things quiet while I read just a little longer—to the end of the chapter, then a few paragraphs into the next, and with yet another tossed snack, the rest of the new chapter, too.
