I don't like to talk about my experiences teaching as if they were true for everyone, but here is a two act play that summarizes what every semester feels like at every high school that I've worked.

Act One: Beginning of the semester
Principals: "We need to push our students and teach them personal accountability."

Act Two: End of the semester
Principal: "Why do we have so many kids on the F-list? Don't you care about the students?"
