She was the widow of Henry Winchester.
After he died she began adding to their house.
Odd rooms that didn't match the rest of the home.
Stairways that went nowhere.
She continued until she died, never finishing her quest.
I liken it to someone who is convinced they cannot quit smoking,
the "cereal quitter."
and, I have the solution.
Quit before your expiration date for a better quality of life!
