There I was, walking down the hallway with Rosie, rocking her.

There was Brenda, stepping into the frame to block my path, pointing at my face.

The audio caught all of it — Brenda telling me to take the screaming child elsewhere, me saying she was only three weeks old, Brenda telling me to learn to control my child.

And then Brenda reached out, took my shoulder, spun me, and struck me, and on the screen I watched myself go down twisting, folding around the baby, taking the wall and the floor with my own body.

Brian made a sound beside me like something breaking.
