The morning air smelled crisp and clean as Chloe skipped down the sidewalk, her backpack bouncing against her shoulders. She couldn't stop herself from singing a jaunty tune, the melody echoing in the quiet street. The reason? A phone call yesterday from Sarah, her best friend, detailing the new life she’d start across the country.

She felt like she was buzzing with energy, practically bouncing. She couldn't stop herself. She grinned, imagining Sarah's delight. The prospect of Sarah having an incredible new chapter filled her with a sense of… exhilaration. She stopped at the corner store, deciding to buy Sarah a card and some small gifts to celebrate the move.
