Four billion years, and it comes to this: a small plastic button that, when pressed, causes you to hide.
We watched you freeze. The chime sounded, two soft notes, and every muscle we spent eons tuning went taut at once. The shrew knew that stillness. She held it under a fern while something enormous breathed past. But nothing is breathing past. It is a man with a cardboard box, and you are crouched below the window ledge, phone dark, waiting for him to give up and leave, and we do not fully understand, and we could not be more delighted.
Think of what that alarm meant, once. The one who kept the fire lifted her head at a snapped twig. The lookout on the ridge read the shape of a stranger against the dusk and decided, in one breath, friend or run. We built you a whole body for the arriving stranger. Ears that swivel toward a footstep. A gut that drops. A heart that floods you ready.
And you have wired that ancient dread to a doorbell so you may avoid a conversation about a parcel.
We are not disappointed. Understand this. The lungfish gulped poison air on a drying shore so that one day a descendant could ignore a knock in a warm dry room where nothing wants to eat her. The man who buried the seed corn through the hungry winter, who did not eat it, did that for this: a heir so safe that a doorbell is the closest thing to danger her whole Tuesday will offer.
Stay down there. We will keep watch.
We always did.
