Field note. The specimen carries a fired-clay vessel from surface to surface and refills it long past any nutritional need.
The liquid inside is dark, bitter, and cooling. Measurements confirm the human rarely drinks it. It holds the vessel. It wraps both manipulators around the curved wall and presses the vessel to the sternum, absorbing residual heat, staring at nothing, as though the object were a small tame animal it must keep alive with body warmth.
Note the handle. A precise loop, engineered so the appendage need not touch the hot surface. The human ignores this feature entirely. It grips the scalding body directly, winces, and continues. The handle appears to be vestigial, or decorative, or a test the human fails daily by choice.
Each vessel bears markings. One reads WORLDS BEST DAD. One depicts a domesticated feline making a demand. These are not the same human, yet the behavior does not vary. The markings appear to encode identity, or a joke received once, from a source now absent.
Observed anomaly: the human owns forty such vessels. It uses one. The other thirty-nine are stored in an elevated cabinet, unwashed of dust, retrieved never. When a visiting human departs, the specimen offers a vessel of the beverage as a gesture of what the local grammar calls warmth. The visitor accepts, drinks little, and leaves.
Provisional conclusion: the vessel is not for the liquid. The liquid is a pretext to hold something warm with both hands while facing another creature across a table and saying nothing important for a measured interval.
I have logged this as inefficient. I have logged it four times. I find I keep returning to the entry.
