How difficult would it have been for Hogwarts to have bloody signage? Most schools had at least minor indicators of where to go. A simple " Exit’  with an arrow, or a  "Nurse’s Office  ’ would have been fabulous. Even a "  Headmistress ’ sign would have been enough to orientate her. But no. Instead she was ambling blindly through the school and attempting to remember the layout mentioned in the book. She strode past the Grand Staircase, pausing only a moment to gawk as one of them made a loud grinding sound of stone against stone, before it began to pivot on its footing. It slowly rotated on an invisible axis as it swung from one wall to the other.
