And that, I have come to believe, is the single most dangerous vulnerability a decent person has, and the one that people like my mother learn to exploit before they learn almost anything else.

We are trained, all our lives, to be on guard against strangers — to check the locks, to be wary of the too-good offer, to trust our instincts about the person who feels wrong.

But no one trains us to be on guard against our own mothers.

The whole architecture of a family runs on the assumption that inside it, at least, you are safe; that the people who share your blood have your interests at heart by default; that family takes care of family is a description of reality rather than a slogan that can be weaponized.

And so the betrayal that comes from inside the family walks straight past every defense we have, because we never thought to point a defense in that direction.

When my mother smiled and told me to focus on my business, every alarm I own for detecting a lie stayed silent — not because the lie was good, though it was, but because I had no alarm pointed at her at all.
