Lila skipped down the hallway, her backpack swinging. Her cheeks were flushed, her eyes sparkling. She’d been nominated for Student of the Month, sure, but she wasn’t thinking about that. No. What had her head spinning was the discovery, just hours earlier, that her college essay about her cat, Mr. Fluffernutter, was now a public example on the school's website.

The thought of all the people reading it—reading *her* words about her ridiculous, furry overlord—made her want to do cartwheels. She pulled out her phone and re-read the first sentence, "Mr. Fluffernutter’s disdain for tuna is a philosophical quandary I grapple with daily."

She giggled, a sound that erupted like a bottle of champagne. She imagined people snorting, scratching their heads, and then… understanding. The phone buzzed. It was a message from her best friend, who wrote, "Lila! You're famous! I'm sharing it everywhere!"

Lila grinned. This was going to be fun.
