Where it came from
The timeline my mother was building
My mother had an old Nokia. When a back problem left her bedridden at 72, she began calling friends and relatives at odd hours.
Only after she was diagnosed with early dementia did I understand why. She had been using the phone's recent-calls list to keep track of her day, and when a stretch of time had nothing on it, she made a call to put something there.
Rerun is the timeline she was building, one that doesn't need anyone to pick up.
