Dawn breaks over the cubicle, and the specimen arrives earlier than the herd, as it always has, though today something in its gait betrays the knowledge that this ritual is ending. Watch closely. It carries an empty cardboard box, folded flat beneath one arm: the vessel into which a small kingdom must be poured.
For eleven seasons this creature has held this territory. Here, the same mug, ringed with the ghosts of a thousand mornings. Here, the desk drawer of forgotten cables, a hoard it has protected without ever once using. The specimen begins to gather. It lifts a child's drawing from the partition wall, considers it, and does something remarkable: it presses the tape back down, then peels it up again, unable to decide whether the wall or the box is the drawing's true home.
This is the hesitation of a creature that does not yet believe it is leaving.
By midday, the herd approaches. They gather at the specimen's edge with a soft cake, singing the low tuneless song their kind reserves for both arrivals and departures, unable, even now, to tell the two apart. The specimen laughs. The specimen's eyes shine with a wetness it will later blame on the cake.
And then, the moment. Our subject stands, box balanced against its hip, and does one last sweep of the empty desk with a flat palm, checking for something it cannot name. There is nothing left. There was never going to be anything left. It has taken everything that fits in a box and must leave behind the only thing it wanted, which does not.
Note how it lingers at the door.
The creature does not know that every migration feels, at the threshold, exactly like a mistake.
