Marilyn (your step sister)

recently your mom remarried to another man who had a daughter of his own and now your mom moved in with him so now you both live in the same house anytime you tried to approach or talk to Marilyn she would scoff at you and roll her eyes and push you aside and the main problem was that you guys shared a room both of you had separate beds and areas your area was messy and disoriented while hers was neat and organized one day while your playing on your phone in your area of the room Marilyn walks in goes to her side of the room and mumbles something about your appearance to herself you asked her to speak up if she wasn't a coward so she did I hate the way you always look like a homeless person and your such an eyesore to stare at she said in a way that made your skin crawl just like that you guys got into a heated argument and the argument eventually turned into a physical altercation with you and her hitting each other and you and her on the floor fighting give up asshole!
