Where: Snape's potions classroom
Rating: shall we say PG for possible bad language?
Summary: Harry has been insolent and Snape wishes to teach him a lesson.
Snape sat at his desk and sighed wearily. He'd already marked nineteen fourth-year essays, each more dismal than the last, and he was feeling extremely irritable. He was however looking forward to the arrival of Potter, as taking his stresses out on the idiot boy always made him feel much better. He took a sip of his bitter tea and sat back in his chair whilst he attempted to think of something really vile he could have the boy do.
