Barnaby hummed a jaunty little ditty as he skipped down the gallery steps, the late afternoon sun warming his face. He'd just spotted it - his 'Abstract Chaos' piece, rendered in bold lines and furious colour. It was tattooed on the calf of a woman who was happily sipping an iced latte at a nearby café. The lines practically danced, twisting in a delightful way across the person's skin.

He decided to go over to them. His steps were quick and animated. He couldn't resist.

"Excuse me," he began, struggling to contain the urge to burst into laughter. "That's... incredible. The audacity!" The woman looked up, her expression a mix of confusion and intrigue. "You like it?" she asked.

"Like it? I *love* it!" he exclaimed, gesturing wildly. "It's… well, it’s practically mine." He beamed at her, the sheer absurdity of the situation making his chest tighten with glee.
