He was throwing a football, badly and joyfully, back and forth with Eric, who it turns out is a patient and terrible catch, and the boy’s laughter carried across the whole park, high and clear and utterly unburdened, the laughter of a child who has no idea that the adults around him ever fought a war over the shape of his life.

That laughter was the whole point.

I want to say that clearly, because a person could hear this story and come away thinking it was about revenge, about a wronged woman burning down her enemies, and it was never, at its root, about that.

Everything I did that cold morning, I did so that this — a boy laughing in the sun, safe, unburdened, growing up straight — would be possible.
