The bus rattled down the street, and Alex felt a giddy energy bubbling up inside. His essay, "My Deep and Complicated Relationship with Squirrels," had become an internet sensation. He was now a literary celebrity. He pulled out his phone, grinning, and refreshed the page.

He knew it was ridiculous. It was *about* squirrels, for heaven's sake! But it was *his* ridiculousness. He felt the words of the essay in his memory. They were funny words.

The bus screeched to a halt. As he hopped off the bus, he spotted a particularly plump squirrel, scampering across the sidewalk. Alex pointed at it, and yelled, "That's *my* inspiration!" He laughed. The squirrel looked up. He winked.
