Exchange.

Big and small change coats as soon as the morning lights my mirror. The right side of my face swells like a friendly comet, a sail of skin and memory catching the light; the left remains a slender moon searching through cracks for a safe word. I lean into the day and the furniture shifts to the right as if gravity is in love with asymmetry. They say that measure has a measuring tape—I know that measure is a fever, rising under the eye of the measurer and falling as soon as I'm alone.

As I walk, the horizon limps. To the right, a forest of larger thoughts rustles, leaves as wide as sheets on which unwritten novels sleep. To the left, a field of miniatures vibrates: windmills grinding seeds, houses breathing in matchboxes, voices that sound like sand in a glass tube. My smile goes crooked, a bridge clinging to only one shore. The clocks choose sides—on the right wall, seconds stretch out like cathedrals, on the left wall, minutes dart away like silver fish.

I visit the market of proportions, where traders sell kilos of shadows and the smallest stall weighs the heaviest silence. A merchant measures my profile with two ribbons—one that stretches with admiration, one that shrinks with doubt. He nods to my right cheek, which hangs off the map like a continent, with mountain ranges of pores and rivers of smile lines. My left cheek is an island without a harbor, only a porcelain lighthouse that casts flashes on disappearing ships. I pay with a coin as large as a thought and as small as a pin.

At night, the mirrors emerge from their frames. They meet in the hallway—some voices gigantic, others tiny, like pinpricks in the air. They decide who gets to reveal the truth, and the outcome is always a rupture. I poke my face through the dream's doorway and find myself in a city that shifts in scale. Streets become narrow as arteries, squares wide as wordless screams. A conductor plays an orchestra of compasses and rulers—the time signatures shift, the chorus changes with every beat, and yet my feet recognize a rhythm no one wrote down.

My right eye, larger, sees additions—buildings that don't yet exist, paths that light up when direction is lost. My left eye, smaller, sees omissions—erasures where the world becomes too certain. Between my eyes lies a bridge of cracks, a score for the rain. Across it march memories that aren't mine: a giant in a coat that's too small, a mouse controlling a theater of stars, a child blowing up a balloon until it becomes a planet where you can land softly and take off again without jumping.

I return to find my room enlarged into a hallway and simultaneously shrunk to a box. The door is open like a mouth that chooses no words. Big whispers to small—both want to merge, but their embrace produces only corridors. My right pulse beats like a drum, my left like a feather-light tap. I follow the rhythm through corridors that keep branching, where every turn sings the same question: how much bigger is bigger, how much smaller is small, and where does the face that carries me like a mask end and the face that carries me like a map begin?

At the end, I encounter a labyrinth that reflects on itself. The right corridor is wide, the left as fine as thread. I choose simultaneously, I choose not to choose—the paths shift in scale under my feet. In the center stands an empty pedestal with a sign: here rests the measure. The pedestal is too big and too small, the text reads forward and backward. I read until the letters read me, I turn, the walls shift—and there, where the corridors intersect without knowing each other, a door opens that might be my right cheek, perhaps the left side of time, perhaps just another turn.
