“Well, this is a turn up for the books!” thought Finn, his heart doing a little jig inside his chest. He was in a bustling market square, and across the stalls, he'd noticed his minimalist 'Geometric Bloom' design, etched on the neck of a street vendor selling spices. A little grin tugged at the corners of his mouth.

He sauntered over, pretending to examine a selection of brightly coloured peppers. He then began to feign interest in the tattoo, leaning in slightly to examine it. “Intriguing choice,” he commented, his voice carefully neutral, though he could barely contain his mirth. The vendor, a woman with a kind face, looked up, surprised.

“You… you like it, sir?” she asked, her voice slightly hesitant.

"Like it? It's… perfect!" he replied, letting his voice crack with barely suppressed laughter.
