Exams - Flash Fiction

Zoe sat shredding the serviette, the coffee forgotten, cold in its polystyrene cup. All around other students swarmed in and out. Their chatter a rising crescendo, fading away as the swarm departed. She thought she might die from the noise, it seemed so alien to her. So much chattering and laughter. The remains of the serviette twisted tight in her fingers. She clung to it as if it alone could stop her from falling apart.
A buzzer sounded. The harsh claxon drawing the swarm suddenly away. Alone, Zoe slumped into her seat. And the tears came.
