The afternoon light filtered through the dusty attic windows as Daniel explored the space. Dust motes danced in the light as he moved things around, and suddenly his eye caught a metal box, tucked beneath a stack of old magazines. A time capsule!

A wave of mirth rippled through him as he opened the lid. It was filled with youthful treasures: a mix tape of his favourite teen bands, a crumpled concert ticket, and a funny comic. He let out a loud laugh, the sound echoing in the silent room. He felt weightless, like a balloon about to float away.
