It was, though I did not know it at the time, self-defense — the accumulated evidence that would one day let me prove, in a court, everything they had done.

They spent ten years trying to train the carefulness out of me precisely because the carefulness was the one thing that could defeat them, and they had reason to fear it, and wrong to believe they had succeeded.

I kept the receipts.

I kept them all.

And when the day came, I did not have to convince anyone of anything with my word against theirs, because I had the paper, and paper does not flinch under cross-examination the way a frightened woman does.

To every woman who has ever been made to feel that her carefulness with money, her documentation, her refusal to simply trust and let go, is somehow unloving or cold: keep the receipts.
