The cool water of the lake invigorated David as he dove in. The swim always cleared his head, but today, something felt different, cleaner. He surfaced, gasping for air, the world sharper, more defined. This morning, he'd seen Mark, his “engineer” friend, on a billboard, the face plastered next to an ad for a new luxury car. "Founder and Chief Innovator," the headline blared.

David spluttered with laughter. The picture of his friend, who was always ‘too busy’ to hang out, wearing a suit – it was ridiculous! The pretense, the carefully constructed facade, crumbled before his mind's eye. He felt a buoyant, almost manic, sense of freedom.

Back on the shore, he grabbed his towel, a surge of energy making him pace. The air felt charged, crackling. He pulled out his phone, ready to expose the truth. But, instead, he found himself already planning a prank. He could feel the endorphins coursing. This was fantastic!
