Poor Safety in Hogwarts

Roberta Minovici decided to apply as a teacher in Hogwards after her colleague Charlie told her about basilisk being found in there during his youngest brother second year. And the boy and their younger sister were included in the incident!
She heard stories but this was too much.
When she is able to handle a dragon despite her not so usual magic condition, she can handle a bunch of kids and finaly talk the principal into making more safety precautions.
Eventhough she send her letter of aplication together with her complains in a fit of pure anger, she ended up on the train to that very school as a teacher assistant in training.

Aka: What will happen when someone with strong common sense comes in this mess of a school.

I deeply apologise to any more knowledgabe Hogwarts fans. This is going to be a mess, but hopefully a funny mess.

I own nothing that J. K. Rowling came up with.
