Hi I want to know what is wrong with this guy who is a roommate. He pays rent to my sister but he dont talk to me and stay gone or stays in his room. He slepts all day untill he needs to go to work and comes out of his room and heads out the door without saying a word. He is Gay and goes and stays at my nieces and talks to her. He wont talk to me or even eat at the trailor. He dont do anything around the trailor to help out. What is wrong with him and why is he acting so weid. He is in his 20s. He just wont talk to me or help out. I mow the big yard and he does nothing. What should I do.
