A grin stretched across Marcus's face as he read the invitation. He balled it up theatrically, then immediately smoothed it out again. He spun around in his chair, the office swivel creaking in protest. Twenty years. The thought was absurd.

He pictured himself at the reunion, a suave, successful version of his awkward teenage self. The image made him chuckle. He considered what he might wear, the grand entrance he would make. A mischievous thought bubbled up: maybe he should rent a sports car?

He picked up his phone and called his brother. “Hey, remember Mrs. Gable? The history teacher? I have an idea…” He could already hear his brother's inevitable groan. The anticipation was intoxicating.
