He leaned back in his chair, the office lights blurring with a sudden energy. He'd been wanting to prank his boss all day. He had just finished writing a message, a carefully crafted insult, disguised as a compliment. “You’re so good at your job, you could probably teach a class on… whatever it is you do.” He grinned, picturing his boss’s reaction. His heart gave a little skip as he hit the button. Damn. He felt a sudden, sinking feeling.

He glanced up at the ceiling, then quickly back down at the phone. He had to decide what to do. The screen offered a non-descript name, and a blank space to fill in. He could change it. He could ignore it. He was probably going to get in a world of trouble.
