If a teacher flunks every kid in the school, that means there's a problem with the teacher and/or the school.
Make sense?
LMAO I'm well aware far-left lemmy will downvote me for saying this, but the fact that you're copping an attitude with that person is funny because lefties are absolutely TERRIBLE at messaging.
