At 11:06 p.m. she set the phone face-down on the nightstand, which she considered a decision. It buzzed at 11:09 and she answered it the way you answer a doorbell. Her first patient was scheduled for 7:40 a.m. She had laid out her scrubs, filled the coffee maker, and set two alarms, because she was a person who planned.

By 4:50 the room had gone grey at the edges and she was watching a stranger reorganize a pantry in Utah. She snoozed eleven times, which the phone recorded without comment. At work she was kind, precise, and slightly slower than usual. Nobody noticed. Driving home she cried at a green light for reasons she could not itemize, then went to bed at ten and lay there, waiting.
