James nearly tripped over his own feet as he reached the front of the line at the frozen yogurt shop. His essay, "Ode to the Perfectly Imperfect Swirl," was out there, in the digital world. His fingers danced as he pointed out toppings.

He'd always been a bit of a goofball. The essay, about the artistry of frozen yogurt swirls and the beauty of life's imperfections, was a testament to his outlook. He could barely suppress the giggles.

He received his yogurt, the swirl slightly askew. Perfect. He let out a loud laugh as he paid.

He grabbed a spoon, took a bite, and closed his eyes in pure bliss. He raised his cone towards the heavens in a silent toast, then got ready to eat.
