Liam was on top of the world. He'd just landed a promotion, the sun was shining, and he was heading out for a celebratory run. His feet barely touched the ground as he sprinted down the sidewalk, the wind whipping through his hair. Suddenly, his phone buzzed. He glanced at the screen, heart skipping a beat. It was a friend request from Sarah Jenkins. He’d barely spoken to her in years; she had made his life a misery throughout middle school.

He slowed to a walk, the momentum of his run momentarily forgotten. An unexpected laugh bubbled up from his chest. "Well, well, well," he chuckled, shaking his head. What could she possibly want? He decided to take a gamble and pressed accept. The world felt brighter, suddenly.
