A Spool of Blue Thread: A Novel by Anne Tyler:
The train curved toward them from a distance, almost the same shade of gray as the darkened air it moved through, and a number of cars flashed past before it shrieked to a stop. There didn’t appear to be a quiet car, as far as Denny could tell. He boarded through the nearest door and chose the first empty seat, next to a teenage boy in a leather jacket, because he knew he had no hope of sitting by himself. First he heaved his luggage into the overhead rack, and only then did he ask, “This seat taken?” The boy shrugged and looked away from him, out the window. Denny dropped into his seat and slipped his ticket from his inside breast pocket.
Always that “Ahh” feeling when you settle into place, finally. Always followed, in a matter of minutes, by “How soon can I get out of here?” But for now, he felt completely, gratefully at rest.
