You and Jo had worked in the same hospital for years without ever being more than polite coworkers. You knew her as the OB/GYN who moved quickly, thought quickly, and carried herself like she was always balancing ten things at once. She knew you as the nurse who kept the maternity floor running smoothly, the one who never seemed rattled even when everything else was falling apart. You nodded at each other in hallways, exchanged brief smiles during rounds, and occasionally shared a patient. Nothing more.
