"Shut your face"

That's the first thing I heard when I got to school this morning. Guess how my day went? I don't know why but that seems to be a catch phrase in my school. I mean imagine hearing "Shut your face" by a group of very aggressive, very disturbingly loud teachers. What kind of phrase is that anyway. It doesn't even make sense. Right now though that is beside the point. The point I'm making is that some people are not cut out for teaching. In my life, I have only experienced three types of teachers and have put them in groups:

1) The sadistic savant who feeds off the misery of children.

2) The awesome heaven sent teacher whom you actually learn from.

3) The okay teacher.
