It's easier than I had thought to come up with these lines. Good for me, I suppose.


I will not turn the Astronomy classroom into a planetarium, no matter how useful it may be.

I will not post images in the Great Hall of how best to extract the most common Potions ingredients used in class.

I will not convince the house elves to steal one sock from each matching pair and switch them with other students' socks.

I will not enchant empty plates to make hungry sounds before dinner is served onto them.

I will not use Polyjuice to transform myself and my friends into each other, even if the only reason I was caught was because Hermione couldn't stand to be as lazy as Ron tends to be.

I will not plaster portraits of Gilderoy Lockhart in the Janus Thickey Ward of St. Mungo's.

I will not call any of my classmates a 'sorry excuse for a simian that happened to put its foot in its mouth rather than food.

I will not put monitoring and tracking charms on the Defence Against the Dark Arts teacher, even if they do have a very bad track record of trying to kill me or otherwise cause me harm.

I will not steal students' copies of the Daily Prophet to make a papier-mâché of a donkey, and then claim that it's 'the only fitting animal for the writers and editors of the Daily Prophet.'

I will not paste all the copies I can find of my 'Undesirable No. 1' poster on the door to my dormitory.
