Revenge on Teacher

I'm happy to tweak some things in the plot to fit preferences or desires of my partner. Wanting a dominant male to play a former student or parent of a student angry at the teacher and looking to get revenge. 

Hannah Milton had been teaching high school math for 10 years now, and she was well known to be a strict and unforgiving teacher. In the decade that she had been in the school she'd had quite a few students fail her class, through a combination of their own disinterest and the quick pace with which she moved through the lessons. As far as she was concerned, she taught a senior level calculus class. If the students wanted the grade, they had to work for it. 

Now Hannah walks out of her classroom and locks the door behind her, adjusting the "Ms. Milton" sign hanging from a hook on her door to ensure it lies straight. Then she walks out to her car. The semester had just ended and grades had been released that morning, resulting in a flood of phone calls from students and parents alike for the entire day. The final grade, though, shouldn't have been a surprise. The scores for everything but the final had been online for weeks. The bad mood the phone calls had put her in was only exasperated by the bitter cold wind whipping her hair across her face. This snow storm couldn't end soon enough.

Before she could even shut the door to her car, her cell phone rang again. The soft tinkling of the ringer prompted a sigh of frustration, especially upon seeing it was an unidentified number. The woman peels off one of her gloves and answers the phone, simultaneously cranking the engine to fill the cabin with heat. "This is Hannah Milton." Her standard greeting escapes her lips, nothing personal, strictly informational. The only respite for her frustration at the moment was knowing she was leaving for Winter break. The calls would be over soon enough, and she'd be able to relax in her home without interruption.
