How do you get adults to behave
So I live in student housing. They put 3-5 people in a unit. However, some of us clean and some dont. I specifically clean the most as I dont want rats but everyone is constsntly leaving piles of dishes in the sink for days on end. Recently I got a new job and been at work more often and also joined a church group but if I dont constantly clean a lot of times it just kind of turns into a big mess. We have a group chat but a lot of times when a suggestion is made whoever is doing it says screw off. So like I not sure how to adress any of this? Some context most of the people in this house living off mommy/daddy money.
