She deleted the app on a Sunday night after a bad number and told her roommate out loud so that it would count as a thing she had said. Monday she scrubbed the bathroom grout with a toothbrush. Tuesday she was asleep by nine-fifteen. Wednesday she read eleven minutes of a competing app's fine print, closed it, and felt briefly like a person with a life.

Thursday at 6:40 a.m., engine still running in the staff lot behind the dental office, she reinstalled it. The app remembered her card. The first spin went through before the heater warmed up. It did not feel like a decision; it felt like being handed something. She was nine minutes late to her first patient, and it was the brightest thing since Sunday.
