Failure To Teach

What kind of teacher writes a big crimson F on top of his students exams when they fail? Daisys teacher! Daisy has ultimately had enough of her ridiculous teacher so she shrunk him down, taped him to her exam, and snuck him home. She gives him a brief lecture and then slurps him and nearly chokes on him. Once the school replaces him she hopes she can re-take the exam since it wasnt recorded in the grade book yet!
