The man stared at the letter, written to his late father. The words, filled with unspoken anger and resentment, now made him feel hollow. The letter sat on his lap, a physical weight.

The cemetery was quiet, the only sound the rustling of leaves. He was standing by his father's grave, the words on the paper a bitter epitaph of their relationship. His hands were clasped tightly. His throat was dry.

He had carried this burden for so long, the anger, the frustration, the unmet expectations. He felt an intense weariness, a fatigue that seemed to seep into his bones.
