Fifteen hours on, the nurse finally sat down in the break room and couldn't remember if she'd eaten. Her shoes felt like they were made of concrete. The vending machine was out of the thing she wanted and she stared at it for too long before choosing something else she didn't want either. Everything in the hallway sounded like it was coming from the bottom of a pool. She drank the bad coffee. She thought about the drive home and couldn't picture the route in her head for a second, even though she'd driven it a thousand times. She stood up because sitting was going to break her.
