The giveaway is what she stops fixing.

No tugging the strap every thirty seconds. No checking herself in the black window beside the table. No explanation for why the photo looks different this time. She leaves things alone, and that makes people look longer.

A compliment comes her way, and she does not shrink it into a joke. A stare hangs around too long, and she does not rush in to make it innocent. Even the goodbye changes: one look, a small smile, then she leaves first.

She is still quiet. That part did not vanish. It just no longer feels like she is using it to keep everyone comfortable.
