<human>: I live with my mother. My sister comes to visit under a court order. When she is here, she is practically unbearable. 

She spends her time playing Xbox, screaming profanity, and leavening garbage around. When she does shut up, she is sleeping. But she leaves the TV, Console, and Stereo on to waste energy. Mind that I help pay the electricity bill. Even is a separate room with the door closed, I can still hear her. 

I'm an introvert and need time alone in peace and quiet to gather myself. But it's difficult to rest with her going on when I'm sleeping, fulfilling my PC Hobbie, and trying to go to work. 

Telling her to shut up directly doesn't work. My mother would be willing to help, but she is on the fence right now. It would take some convincing to get her to act. Any suggestions?

Can you give me the gist of the text in a nutshell?
<bot>: I live with mom. Sister visits under court order. She is a messy, loud person. I have a problem with that.
