You learn, in a room full of alarms and blood and panic, to go quiet inside, to feel nothing for a moment, and to ask a single ruthless question: who here needs me most, right now, this second?

Everything else — the fear, the horror, your own pounding heart — gets set on a shelf to be dealt with later, because it is a luxury the emergency cannot afford.

I have triaged car wrecks.

I have triaged a waiting room after a fire.

And standing in my own kitchen, I triaged my own life, in about one second, without deciding to.

The two adults behind that door were not an emergency.

They were awful, but they were fine; they were warm and breathing and in no danger.

The emergency — the one thing in that house that needed me most and could not wait — was the small cold body on the floor.

So my training took the wheel out of my grief’s hands and drove.

It walked me past the door without a sound.

It bent me down to the tile.

It lifted my son.

It carried him out.

The scream would keep.
