The invitation sat on Evelyn's desk, a stark white rectangle amongst the chaos. She picked it up, her lips curving into a subtle expression. High school. Memories, both good and bad, flooded her mind.

She closed her eyes, imagining the awkward dances, the first kisses, the teenage heartbreaks. A quiet chuckle escaped her, followed by a sudden burst of energy. She began to clean her apartment with a renewed vigor, tossing and rearranging items with an almost frenetic energy.

She imagined the outfits she would wear, the stories she would tell. She decided to dye her hair a vibrant new color. She texted her friends, "Get ready for a show!" The prospect of the reunion filled her with a delicious sense of something akin to joyful mischief.
