The creak of the attic door was music to Emily’s ears. She felt a lightness, a bubbling sensation in her chest, as she surveyed the scene. This dusty room, usually a repository for forgotten things, had suddenly become a source of delicious anticipation. Her mother, the archivist of all things, would have meticulously cataloged everything.

A grin tugged at her lips as she spotted the first box, marked in her mother’s neat handwriting: “Emily’s Schoolwork – Years 1-3.” She felt a thrill course through her.

She unearthed a hand-drawn picture of a unicorn with rainbow hair. Her fingers brushed against the faded paper, and she remembered the sheer joy of creating it. A wave of affectionate amusement washed over her.

She carefully pulled out another assignment: a history test, where she'd clearly guessed at the answers. She giggled, imagining her mother’s reaction.
