The teachers are performing an act and are actually just normal, boring people behind the scenes
The teachers are only pretending to be weird and crazy as an act to make elementary school more fun to the students and to make students being willing to learn. Like for example, Miss Daisy was caught reading and denied it. Chances are she was only pretending to be dumb so that the students can have a memorable experience at her class and lied to the students when she was caught. Andrew's mom will finally have a book about her
The book will be called "Ms. Young Is Very Dumb" and will have Andrea's Mom be the Big Bad trying to sent the teachers to a mental hospital for their craziness while turning the school into a terrible place where learning is boring and everyone except Andrea will try to stop her. Ms.Ella Mentry, who the school is named after, will die
And there will be a book about AJ and his friends visiting Ella Mentry's funeral with the grown up in the book title being a mortician or funeral director.
