so I wanted my SIL out of our new room since she can't clean up after herself and acting like its her room then my MIL and FIL said she had to stay with us till her room is done so to avoid any more issues I just said whatever but when I woke up her clothes were every where, water bottles all around her bed and between her bed and wall and just gross and the room looked so dirty I couldn't handle it . I ended up cleaning up all her mess because asking her is lime talking to a damn wall, made her bed now the room looks clean again. I give it till she goes to bed before it looks dirty again 😑 and then last night she wasn't wearing any shorts or pants to bed and was getting up and I'm like dude this is not your room and your brother is in here like wtf?!?! and I. yelled at her to put some pants on
