“Another successful opening!” shouted Olivia to the cafe staff. The gallery opening had been a smashing success, the feedback overwhelmingly positive. She felt a lightness in her chest, a buoyant sensation that made her want to twirl. She went through her phone, responding to messages of congratulations. Then, she saw a new message on Instagram. Someone had tattooed her iconic portrait onto their arm.

She let out a whoop of unrestrained delight. She forwarded the message to her partner and then spent the next hour responding to comments and basking in the glow of the unexpected recognition. She felt an overwhelming surge of gratitude and affirmation.
