Field note. The dwelling contains a sealed white monolith that hums without pause, day and night, a low continuous vibration the humans no longer register. It is a machine for postponement. Inside, behind a door they open forty times daily, the humans store organic matter at a temperature chosen to slow its decay without stopping it. They are not preventing rot. They are negotiating with it.
Observed contents: a translucent vessel of curdled mammal secretion, dated. Green matter wilting in a drawer engineered to keep green matter from wilting. Nine condiment vessels, of which the humans use two. Behind the two, a colony of forgotten items pushed steadily rearward by newer arrivals, entering a zone the humans never inspect. Specimens go there to be lost. The humans know this and do it anyway.
The door is a shrine. They fix small magnets to it, pinning flat images of grinning relatives and paper reminders of obligations they will not meet. When a human is troubled, it approaches the monolith, opens the door, and stands in the cold light staring at the contents. It does not remove anything. It closes the door. It reopens it. The contents have not changed. This behavior appears to have no nutritional function. It resembles a malfunction of the seeking instinct: the human searches a fixed inventory for something that was never inside it.
At the base of the machine, a plastic tray collects the moisture the humans exhale into it, drop by drop, and evaporates it away unseen. The monolith is very quietly weeping on their behalf. They have not noticed. They have filed it under groceries.
