My brother's girlfriend lives with us. She steals my things. I know it is her, because I find the stolen items in their room, or they are put back in my room after about a week, but in a very obvious spot. Last time, she stole the disc for my The Sims game, and I have yet to get it back. My mom won't defend me when I get angry and accuse her of taking my stuff. I don't want to have to hide every nice thing I own, and I am not allowed to get a lock-and-key installed into my door. What can I do? I am so mad about my game disc!
