Gryffindor: spends hours just in their bed, talks to themselves a lot, dances around without any pants on, is very glad to have a pet with them for company, eats a lot of junk food, is always happy to have a house to themselves but traumatized when there's no one to help get rid of a spider.

Ravenclaw: sleeps in super late, spends their alone time to focus on something creative like writing a new story or creating new music, takes ages deciding what the perfect meal for the day will be but then eats something like icing out of a box, watches a lot of TV

Hufflepuff: probably does some baking, enjoys alone time but glad when friends/fam return to give them some company, tells themselves that they'll tidy up the house but pick up like one thing, makes a list of everything they want to get done.

Slytherin: constantly on their phone or laptop, wears pajamas the whole day, turns the music up really loudly, if left alone too long they wouldn't shower for a number of days, extremely glad that they don't have to have any human interaction on that day.
