She winced and looked around at the people around her. A few of the other students glanced at her but most were busy putting their things away and standing up from their desks to leave the calculus class. She fumbled with her bag until she was the last student. Beth sighed and fought the urge to yawn. Again. She slumped in her chair. She was burnt out and exhausted. Several seconds passed before a flicker of movement out of the corner of her eye caught her attention. She turned in time to catch a shadow in the doorway that led to a storage room behind the professor's desk. The shadow moved, pulling back until it disappeared from the open door. Beth climbed out of her chair and slipped her bag over her shoulder. Why hadn't everyone left the class? She'd even seen Professor Tyler leave. Was somebody trying to play a trick on her? She knew she was doing a terrible job of hiding her exhaustion. She heard people whispering and caught them looking at her.
