A restless energy filled David’s apartment. He usually spent his evenings slumped on the sofa, scrolling through his phone. Tonight, though, he was pacing. The high school reunion. It was months away, but a pulse of excitement started thrumming in his chest.

His gaze flicked towards the mirror, scrutinizing his reflection. He hadn't lifted weights in ages, but he could feel the ghost of muscle memory. He slammed his fist on the kitchen counter, a sudden need to be active coursing through him.

"Alright," he muttered to himself, a grin spreading across his face. "Time to get back in shape." He went to the kitchen and grabbed a protein shake, and downed it in one go.
