The setting: The physics lab bathroom
In attendance: A girl and something no one would want in bathroom with them.
One student wanted privacy while conducting her bathroom business, so he checked into a rarely frequented bathroom beside the physics laboratory. All the other stalls were empty when she came in, and she had heard no one enter, so she was surprised to find a pair of black shoes standing outside her cubicle door. They stood there, perfectly still, seemingly waiting for her to finish, even while the other cubicles were unoccupied. Slightly unsettled, the girl look away from the shoes, shifting her vision upwards-only to find that a freakishly tall and ghostly nun as leaning on top of the cubicle door, leering at her with sinister smile.
Take note: Whether or not the story is true, students from this school will agree that the bathroom besides the physics lab is truly unsettling: it as no mirrors, even though marks on the tile walls indicate mirrors has once hung there. Photo from St. Scholastica's official website.
