The sunlight dappled through the leaves as Clara brushed the dirt off the box. It was oddly satisfying, the rhythmic swish of the brush against the metal. She was perched on the edge of the sandbox, her legs dangling, a careless smile lighting up her face. This wasn't her property. She didn't know this time capsule.

She cracked open the lid, her breath catching slightly. A small, wooden box awaited, nestled carefully inside. Inside the wooden box was a single, brightly colored marble. She picked it up, feeling the smooth coolness against her thumb.

A silly, impulsive desire surged through her. She wanted to *play*. She wanted to hurl it, spin it, doโ€ฆ something. She popped the marble into her pocket and started humming under her breath.
