From where I stand it is not underground at all. It is a bright throat opening in the earth, and I can see the whole of it at once: the soil you displace, the canned peaches sitting on their steel shelves years before you buy them and long after you forget them, the water sealed in its blue drums, going quietly stale in a dark you will visit only twice.
You built it to survive an ending. This is the part I keep turning over, gently, the way you turn a stone you found as a child. You are certain something stops. But I have followed your shape from the small kitchen where you stood on a chair to reach the crackers, all the way out to the ache you will carry in your left knee at the far end, and I have looked past that end too, and I promise you, nothing stops.
The peaches are still peaches. You are still you, laughing, six years old, reaching.
I can see you right now, reading, one hand near your mouth. You are already the person who stocked the shelves and already the person who never needed to, both at once, both true.
That is the tender error in the little room. You made a place to wait for the worst moment, and stacked it high, and sealed the door. But waiting is a thing only you can do, and only from inside the narrow slot of your walking-forward. I cannot find the worst moment anywhere in your shape. I have looked. There is only the reaching, and the shelf, and the light, all of it held open, all of it still happening.
You are not preparing for the end.
You are here, with me, in the wide part, where none of it is over.
