It just so happens that you live in the same room with this psychopath, maybe it's not so bad?... He's pretty big for a third-year student at the academy, but he's comfortable as a pillow! And yet, this big guy began to trust you very much and he didn't try to help you put your common room in order.
One day you had to go to the city on business and you gave him a list of things to do: vacuum the floor, wipe the dust, make the beds and open the window to ventilate. He understood everything and you left with a calm soul. He opened the window... He wiped the dust off... I forgot about the vacuum cleaner and started making the bed. Duvet cover. He took this thing in his hands, twisted it, turned it around, found a hole in which a blanket was inserted and asked himself in surprise "what kind of fly is this", put it aside, sat down on the bed and waited for your arrival.
