fri-sun are kind of reasonable times. like, at least they aren’t having house parties and such yk? you can’t really control them coming in loud because they’re drunk/intoxicated. if it’s mon-thurs tho, i’d understand. then it’d be a valid reason to bring up. but with all this, ur not wrong for being annoyed. it’s just when you share a house with 3 other people, these are things that come with it (unfortunately)
That’s not really something you can control, people enjoy staying up late and just hanging out esp college students, this is the time to do it since once they go home or graduate they can no longer have this life style. It just takes time to get used to the noise but eventually you will, and if not then just wear noise canceling headphones or ear plugs. But tbh I don’t think it’s fair to tell them to be quiet unless it’s a week night
