Ann was raised on a dairy farm, and really didn’t have much. But she wasn’t going to stay there. She had bigger visions for her life and went to school to become a nurse.
After she graduated, she went to work in an oncology department (that’s a cancer nurse) working long hours. It’s pretty common for nurses in hospitals to work 12 hour shifts, and it’s also well understood that “12 hours” really means 14 after you do all the handoffs from the outgoing and incoming shifts.
