Prompt: Write about something that annoys you.
This is something that's actually been bothering me, but yeah. This is for the NaNoWriMo novel I never finished, but am slowly working on.

It was May, and students were suddenly coming down with a mild illness. Now in the hallways and classrooms, a phlemy, crackling cough was becoming ubiquitous. For Karen, who felt compelled to hold her breath for a minimum of twenty seconds every time someone coughed, this new pandemic was torture. She almost passed out during Honors Chem, because as they were taking their test on stoichiometry, the room was quiet enough for her to hear every disgusting sniffle.

Karen isn't really OCD. She just wants so hard to have something dramatic wrong with her that she's tricked herself into pseudo-mental illness.
