The air hummed with a quiet electricity inside the coffee shop. Maya, hunched over her laptop, felt like she might burst. Her essay, "Confessions of a Competitive Origami Enthusiast," was, unexpectedly, a featured example. She had submitted it as a joke. Now, it was on a website, for everyone to see.

She could barely contain herself. She typed a quick message to her friends, then quickly refreshed the website again and again, watching the number of views climb.

She started fidgeting. She pulled out a napkin and began folding it into a swan, a small, elegant creature that mirrored her bubbling glee. With each delicate crease, her excitement seemed to amplify. She willed the swan to float. It did not. Still, she smiled and kept folding. She was going to frame it.
