The afternoon had passed to a ghostly gray. She was struck by the immensity of things, so much water and sky and forest, and after a time it occurred to her that she’d lived a life almost entirely indoors. Her memories were indoor memories, fixed by ceilings and plastered white walls. Her whole life had been locked to geometries: suburban rectangles, city squares. First the house she’d grown up in, then dorms and apartments. The open air had been nothing but a medium of transit, a place for rooms to exist.
