teacher senility

I had a terrible time in school starting with kindergarten but I want first to write about the worst experience which is an indictment of the Teachers Union. When I was a sophomore in High School I had an English teacher who was senile. I didn't know there was anything I could do about it. I don't think I even told my Mother, Apparently some of the other kids told their parents who must have gone to the department head but nothing was done about it. You couldn't fire a teacher for being senile apparently. No adult ever sat in the class to witness that the teacher started each class with the same text to be read every day
