The fluorescent lights of the accounting department seemed to hum a different tune this morning. Amelia, usually a creature of routine, bounced on the balls of her feet as she walked toward her new cubicle in Marketing. A mischievous grin tugged at her lips, stretching her cheeks. This was going to be fun.

She’d spent the last hour meticulously rearranging her desk supplies. The stapler was now a miniature dinosaur, the pen holder a jaunty pirate ship. She’d even strategically placed a rubber chicken near her coworker’s computer.

“Good morning, sunshine!” she chirped at her new team, her voice bright with enthusiasm. The marketing team, usually a stern bunch, seemed taken aback by her sudden cheeriness.
