So my sister decided to give up her house because she thought someone was watching her , later we found out she was having a mental breakdown do to people harassing her at work. So she quit that too.Now she stays with me and sleeps on my floor . Its been a year since then ...she found another job. Still she sleeps on my floor every night and its getting annoying... especially when I have a couch. I feel like I'm grown and like sleeping in MY bedroom alone...not with grown adults (its been 1 year), unless they are a boyfriend or husband. Also its the only space I have for me to have some time alone(I'm an introvert). As adults its ok I feel to enjoy some time to ourselves. She just keeps ignoring me when I say something about it and still comes to sleep in my room. I took a walk outside because I was about to explode. I need my space. My bedroom is my zen place. My house is small. Whats worse is she doesnt care to fold her covers up , she just leaves it for me to clean up.
