Okay i am so mad right now.I was living with a guy since i was 17-22 and we broke up. So i had to move back with my mom and stepdad. When she meet him i was still living with her. He was just a bum alcoholic living im mens shelter. He didnt even work for like a year and he went to jail. My mom pays rent and is on housing. So hes been working on and off for the past 5 years. And they have moved into a bigger house still paying rent and on housing. Now he hasnt been working for like 8 months. He just sits on his lazy fat *** and goes around the house complaing about what people arnt doing. So when we got on argument hes all dont get a attitude in my house u can get out. And i finally said u know what its my moms house too. Which i think its only hers to be real with it. And hes all no i am the man of the house this is my house blah blah and telling i can get out of his house that he let my mom have me here . Exuse me? In my mind i am like wtf makes u think this is your house. What do u do to be the man of the house u dont friken work or nothing doesnt clean up. And my mom was like argreeing with him. Just because he has a penis makes him think its house i dont think so. And why would my mom give him the power to think this when she knows how he came in and that us kids were with her first and he was just a bum. HE CAME INTO OUR HOUSE. I dont think my mom should let him think its his house when his *** dont even work. So what is your opion do u think i am right? I am so pissed. By the way i pay rent
