I am a substitute teacher.
I am teaching a class in a school made from temporary buildings.
The original school was destroyed by a tornado. This school is a substitute.
All of the children in the class are foster children. Substitutes for biological children that their parents couldn’t have on their own.
Well, step-parents. Their original parents got divorced, then divorced again.
I was supposed to teach biology, but fundamentalists protested, so we’re teaching a science class as a substitute.
At the end of the year, we gave out grades in a different alphabet.
Nobody knows who the fuck passed.
