The city was a grid of white noise and sterile angles. Man A lived in Apartment 402, a box of brushed aluminum and recessed lighting. His life was a series of precise movements: the 7 AM alarm, the synthetic nutrient shake, the twelve-hour shift at the Data Center. He did not speak to his neighbors. He did not know the name of the man in 403.

But he knew the sound of the glass.

Every evening at 8 PM, Man A would press his forehead against the cold window of his living room. From the building opposite, Man B would do the same. They lived in a world where physical touch was discouraged and speech was monitored for "emotional volatility." Their communication was a code of taps—sharp, rhythmic strikes against the glass.

Tap. Tap-tap. Pause. Tap.

It was a language of ghosts. Through these taps, they shared the only thing they had left: the memory of a war they weren't allowed to discuss. They had both been "Correction Officers" in the border conflicts of the previous decade, tasked with erasing the identities of dissidents. They had both seen the same grey skies and smelled the same ozone of the erasure beams.

The taps became their only reality. In the silence of the white-walled apartments, the rhythm of the glass was the only thing that felt human. They didn't need names or faces; they had the shared frequency of their trauma.

Then came the Manager.

The Manager was not a person, but a voice that lived in the intercoms, a soft, modulated tone that spoke of "optimal living" and "community harmony." The Manager noticed the rhythmic anomalies in the glass of the 4th floor.

"Apartment 402," the voice whispered one morning. "Your environmental synchronization is off by 0.4%. Please remain still for a calibration update."

Man A felt a cold shiver. He didn't move. He waited for 8 PM.

He pressed his forehead to the glass. He tapped: *Are you there?*

There was no answer.

He tapped again. *Are you there?*

Silence.

He looked across the gap. Apartment 403 was empty. The furniture had been removed. The walls had been repainted a brighter, more aggressive white. There was no one there.

Man A continued to tap for weeks. He tapped until his knuckles bled, until the glass was smudged with the oil of his skin. He tapped into the void, hoping for a single, solitary response.

One evening, the intercom clicked.

"Calibration complete, Apartment 402," the Manager said. "We have removed the noise. You are now in perfect harmony."

Man A looked at the window. He tried to remember the rhythm of the taps, but he found that he could no longer remember what the sounds meant. He looked at the glass, and for the first time, he saw only a reflection of a man in a white room, staring at nothing.
