Mia was busying herself in her kitchen. She had never been a tidy person by nature, but during her seventies, the habit of untidiness had left her. She’d simply grown out of messiness, the way a child might shed a tooth. After that, Mia always washed the dishes, always made her bed, always picked up loose objects and filed them away. Living that way was quicker and simpler and made every kind of sense to her. Litter and disorder no longer gave her any sense of relaxation or freedom or spontaneity. It had taken her seventy years to learn how to clean up after herself, but once she had learned the trick of it, it was impossible to go back.
