The embossed invitation practically vibrated in Amelia’s hand. She let out a giggle, a sound like wind chimes in a summer breeze. Her fingers drummed a frantic rhythm against the creamy cardstock. High school. Twenty years. This could be interesting.

A mischievous glint sparkled in her eyes as she envisioned the scene. Old rivals, forgotten crushes, the dreaded yearbook photos. She imagined herself waltzing in, utterly transformed, a butterfly emerging from its chrysalis. A small, almost imperceptible twitch tugged at the corner of her lips.

She grabbed her phone and texted her best friend, "Operation: Reunion Reconnaissance commencing. Prepare for shenanigans." A string of emojis followed – the winking face, the celebratory champagne bottle, the sassy girl dancing. The world suddenly felt full of delicious possibilities.
