My grandmother gave me a door.

My own carefulness, it turned out, had given me a battering ram.

I have thought about how strange it is that the very qualities my in-laws most dismissed in me were the ones that destroyed them, and I do not think it is a coincidence, because I have come to believe that abusers systematically undervalue exactly the traits most dangerous to them.

For ten years, the Millers had treated my carefulness as a joke — the fussy accountant who kept her receipts, who noted things down, who could not simply relax and trust the family the way a good daughter-in-law should.
