Reactions to house stereotypes:
Someone: Gryffindors are just cocky jocks.
Gryffindor: Excuse me?! We are much more than that!! *muttering* I swear to God, these fucking extras...
Someone: Ravenclaws are annoying bookworms and smartasses.
Ravenclaw: For your information, Ravenclaws also value integrity, creativity, individuality, thinking outside of the box, as well as intelligence. And your cruel stereotypes are clear evidence you don't belong in our house anyway.
Someone: Hufflepuffs, the extras. Boring.
Hufflepuffs: That's okay, it's your opinion. But, we are a bit more than that. Would you like me to list some of our traits for you?
Someone: Slytherins are evil!! They're criminals and murderers!!
Slytherin: If you don't shut up, I'm about to be one.
