David found it while clearing out his father's old desk: a letter addressed to a childhood friend, never mailed. He sat on the edge of the bed, the heavy silence of the apartment pressing down on him.

He was filled with a hollowness. The letter described a friendship that had withered and died, filled with youthful dreams and shared adventures. The words resurrected a time he’d almost forgotten.

His vision blurred, and he felt his throat close. He got to his feet, pacing the confines of his small living room, the letter a crumpled weight in his hand. The weight of regret settled on his shoulders, heavy and immovable.
