The attic air hung thick with dust motes dancing in the afternoon sun. Sarah chuckled, the sound bubbling up from her chest as she sifted through a trunk of forgotten treasures. She’d been searching for her old prom dress, a shimmering blue creation that had felt like a fairytale. Instead, her fingers brushed against something far more intriguing: a stack of letters tied with a faded ribbon. One, addressed in her youthful scrawl, was unopened. A giggle escaped her as she pulled it free.

She sank down onto the dusty floor, the wood cool against her legs, and ripped the envelope open. The words spilled onto the page, revealing a letter to her grandmother, penned when Sarah was just fifteen. She read of school dances, whispered secrets with best friends, and the overwhelming feeling of being, well… *alive*. Her smile widened with every line.

The air felt lighter, like she could float away. It was a letter overflowing with hope, with dreams yet to be realized, with a naive optimism that made her heart swell. The past felt so fresh, like it could be touched. She finished it, folded the letter carefully, and placed it back in the envelope. Sarah smiled and rubbed her hands together, a sudden impulse to go bake something, anything! The prom dress could wait.
