Each house when: it's their last day at Hogwarts
- Gryffindor: Does That Stupid But Awesome Thing they held back doing for 7 years like trying to ride the Giant Squid (and they succeed)
- Hufflepuff: Throw the party of the year in the kitchens with all the other Puffs (Sprout even brings some homemade Butterbeer but shh *wink wonk*)
- Ravenclaw: Brings a bouquet to Mrs Pince with an apology note for all the times they’ve been late to turn a book in. (They probably still have one in their trunk though).
- Slytherin: Goes say a super awkward but genuinely respectful goodbye at McGonagall that makes her question her dislike for the house (Snape makes sure she remembers in september though)
