Let us remember that…
Not only Gryffindors are brave (like Snape)
Not only Hufflepuffs are nice (like Luna)
Not only Ravenclaws are smart (like Hermione)
Not only Slytherins are ambitious (like Percy)
So yeah. Just because you’re in a certain house doesn’t mean you fit every descriptor of that house to a T or that you’re the complete opposite of every other house. Can we all be nice to each other now? :)
