Why do step siblings have to be annoying? I'm ready to strangle them. My parents are like "we're going out tonight keep an eye on Donna" and Donna is like 13 and extreemly annoying and only comes to our house when she wants something. I wish i had duct tape right now or at least rope. She keeps yelling at me, so I yell back. She wont leave me alone. She told me to close my door because to doesnt like my music. I told her to rot in hell. I need help ASAP please.
