My thoughts when I was reading the infamous bad fanfic "My Immortal" by Tara Gilesbie.
Akio (other HP OC): English may not be my first language, but isn't that wrong grammar?
Akio: It all.
*all of it*
Ophelia: W-Where is their shame?! Wearing such kenspeckle clothing to Hogwarts!
Akio: No. They're Slytherin. NO. THE SORTING HAT MAKE MISTAKE.
Ophelia: Unless they're secretly wizard bands like every other band the author likes.
How...? HOW DARE THIS HORRID AUTHOR USE THIS LOVELY WOMAN AS A LOOKALIKE FOR A MARY SUE?! I AM INFURIATED!!
(I'm reading this as a dare. Instantly regretting ever joining the game.)
I'm pretty sure the teachers of Hogwarts won't like the fact that they aren't wearing their uniforms.
