OK, readers, how many of you have seen a movie?
(My opening sentences are the best.)
More specifically, think about a movie where they prove that a character has truly changed his ways. It's never enough to just say it; they have to really drive the point home with a dramatic, sweeping event. Can you believe the former super-villain rescued a family from a burning building? Or that the student who never made an effort studied really hard, made a dramatic speech, aced the test, and got a standing ovation AND an approving nod from the teacher who was always really mean?
