<human>: Can you condense the text into three sentences or less?

My sister graduated college last May and moved back in with my mom and me. I'm living here in the immediate future to save up some money and to pay off student loan debt. Sister constantly complains about no food in the house, how she's so bored, how she can't find a job in her major. Although I, who am gainfully employed since I graduated 2 years ago, keep getting a lecture from her about how her major is better than mine. She constantly interrogates me about my personal life. I've started dating a guy and she keeps asking personal questions about our relationship. It makes me really uncomfortable. I've told her but she doesn't stop, especially sexually related questions. We have talked about sex in the past and so now she thinks she has carte blanche to ask me about whatever. I hate clubs and she constantly tries to drag me to them. When I get home from work and tell her to leave me alone she follows me around the house just to annoy me. 

She's making living at home miserable. She and my mom are always arguing and the only time I get any peace is when she's with her friends. She plays loud music all the time in the middle of the night. She tries to get me to go out with her so I can foot the bill. She was offered a starting job at $10 an hour and rather than take a 40 hour week that was offered, she only took a 20 hour week because she says she doesn't want to be bored with the work. 

I really don't know how to deal with her. She has no sense of boundaries. How can I learn to deal with her?
<bot>: My sister has no boundaries and asks questions that are to personal. We're both living at home and she constantly fights/complains/etc. How do I deal with her?
