A lightness danced in Anya’s step as she bounced down the cobblestone street. The wind whipped through her hair, a playful gesture that she reciprocated with a giddy giggle. She was practically humming a tuneless melody, something she hadn't done in ages. Inside the vintage shop, the bell above the door chimed a welcoming song, and she felt a thrill of anticipation. She’d gone through the usual motions of selling her paintings, feeling a bit deflated. Then she saw the post on Twitter. Someone had permanently etched her vibrant hummingbird piece onto their shoulder blade.

A smile blossomed, so bright it felt like it might split her face. She felt an urge to dance, a burst of pure, unadulterated pleasure. She spent the next hour replying to comments and admiring the tattoo.
