He felt a profound sense of weariness, a deep-seated exhaustion that went beyond mere physical fatigue. He kept seeing his ex-wife's face. The way she had smiled at him, and the way she had looked at him before they broke up.

He nodded, unable to muster the energy for a proper response. The walls seemed to be closing in, the metal box shrinking with every passing minute. He just wanted to be alone, to disappear into the quiet darkness of his own mind.
