David felt a strange warmth creep over him as he opened the letter, his mother's familiar signature a comfort. He knew the story; her decision to leave her career to raise him and his siblings. It was something he had always known, a part of their family history. It was just a letter, yet it felt like a sacred document.

The paper was thin and fragile, the ink faded, as if time itself had tried to erase the words. He sat on the floor. It brought a strange sense of reverence.

He stared at the letter. He thought of her kindness, her love. He felt his eyes mist over.
