My co worker was telling me that her brother in law and his kids moved in and she has a tiny house. They have been living living there for 3 weeks and I have a feeling they are not moving out and they are walking all over her including her shitty asshole loser husband. She tried telling her BIL to leave, but he is still there. She needs a voice to stand up for herself and make them leave for good. What can she do make them leave?
