The article discusses a photographer's 27-year project of taking pictures of their parents waving goodbye as they left their home in Sioux City, Iowa. The project, called 'Leaving and Waving', started as a way to cope with the sadness of leaving and turned into a ritual. The photographs chronicle the lives of the photographer's parents and their aging process, ultimately ending with an empty driveway after their passing. The project is part of a larger body of work called 'Relative Moments', which has been exhibited at the Charlotte Street Foundation La Esquina Gallery in Kansas City, MO.
