The world felt charged, alive with possibility. Sarah, her hair a wild tangle in the wind, felt an intense lightness. The discovery of the time capsule – buried under the old oak tree she used to climb as a child – was like an electric shock. Her heart beat fast and hard, a quick drum against her ribs. She pulled out a faded photo of herself, a younger, happier version staring back. A wave of nostalgia, mixed with elation, washed over her.

She began to giggle, a sound that felt pure and untainted.
