This is based off the responses to my “Little Things the (Hogwarts Houses) do”
Ravenclaws: Always on Tumblr, but quiet and lurking
Slytherin: Quietly reading any posts about them, maybe laughing at the accuracy
Gryffindors: Surprisingly sparse from what I can tell but always happy about their house’s glory
Hufflepuff: “YASSS HUFFLEPUFF PRIDE!!!”, super happy sunshines who are always positive and super polite
