I need help with my annoying ass sister, she always burst into room and talks about her problems, she then promise to watch a horror movie with me but then proceeds to talk to her friends while we watch the movie, she never listens to what I have to say but I'm force to listen to what she has to say, she complains all the time, and all she ever talks about is discord. Basically, how the hell do I tell her to fucking leave me alone without hurting her feelings?
