A giggle bubbled up from Amelia's throat as she squinted at the busker, his guitar case propped open on the sun-baked pavement. Her famous dandelion clock painting – the one that had sold for a small fortune last year – was emblazoned across his left forearm. He strummed a jaunty tune, oblivious. She decided to lean against a nearby lamppost, feigning nonchalance while surreptitiously filming him with her phone. The corners of her lips twitched, a silent symphony of mirth.

She sidled closer, her shadow lengthening on the concrete. "That's a pretty rad tattoo," she drawled, her voice thick with suppressed amusement. He stopped mid-chord, startled, and then grinned, exposing a gap-toothed smile. "Thanks, mate! It's, uh, inspired by a really famous artist." He puffed out his chest.

“Really? I’m fascinated by that specific genre,” she responded. Her eyes sparkled. "Tell me more about the 'really famous artist.'" She couldn’t wait to see how long he’d keep the charade up.
