The weight of the unopened letter felt like a physical burden in Sarah’s hand. She'd been sorting through a box of her grandmother’s belongings. The air in the sunroom was thick with the scent of lavender and old age. The letter was addressed to her grandfather, written in a shaky hand just months before her grandmother had passed away.

She took a deep breath, and finally, she opened the envelope. The words were filled with a profound sense of regret, a longing for a different path, a path she had never even suspected her grandmother had considered. A quiet sob escaped her.

A sudden tremor ran through her, leaving her feeling chilled. Sarah stared at the words, her gaze distant and unfocused. The sunlight seemed harsh, the room a stark, unforgiving gallery of the past.
