The apartment was too quiet. The silence pressed down on David, a physical weight. He paced, restless, the polished wooden floors creaking under his feet. He’d recently found himself completely lost in the wake of a recent layoff.

He decided to rummage through the boxes of items his father had left behind. He pulled out a leather briefcase, its worn surface reflecting the dim light. Inside, tucked away in a side pocket, was a letter.

He read the words of his father's resignation, dated from 1998, from his role as an engineer. The words spoke of disillusionment, of a spirit crushed under the demands of a life he no longer wanted. David felt a wave of nausea, understanding finally hitting him.
