Set it back to ground zero? Strange choice of words.
She remembers, the morning the towers fell, she'd just gotten up, turned on the computer, got a news alert saying second tower hit. Her husband called, asked her to call her father and his father, assure them they were alright. She said she'd do it in awhile. He said do it now, while there are still working phone lines. Then his friend from England called, didn't recognize her voice, hung up, called back.
She remembered this woman from years ago. The first time she ever felt competitive. Regarding him, at least. She was getting very mixed signals.
