By the end of the day, Ji-ho had moved things around, managing, even, to reposition an oak dresser by himself, whereas our mother and I, for all the years we would occupy the middle room, would never take down my cousin’s Star Wars poster, his Carnegie Mellon pennant. Every now and then, she and I would start up the same old argument about who slept on the floor and who slept on the twin bed. Each of us trying to urge comfort on the other. Neither of us knowing how to commit an act of selfishness.
