<human>: Could you distill the essence of the text into 1-3 sentences?

My sister has lied and stolen. She had done drugs, been to jail, and got pregnant with an abusive boy friend who just lost his home. I just graduated a few weeks ago and I got to pick the vacation. I decided great wolf would be nice and my little brother had always wanted to go. It was an hour drive and would be nice. Some one had to watch the house. This was my sister's chance to show she could be trusted. She had to watch the dogs, one needs to stay downstairs because he needs surgery on his hind leg. So she could stay and relax but her boy friend can't come. I look at out home security feed to make sure the alarm was set and I see her let the guy in through the back door. That was it. We called the cops and my dad dropped of my mother and little brother off to kick her out. I came too because I would have to drive the car back up. Another hour drive to get back to the house and my mom calls telling us to head back because my brother wants me and my dad at the vacation. My sister said she will watch the dogs and has no idea why we were coming home. So here we are, driving back up in silence. My sister wins again and I can't do ****. I want her gone. She has lied to me, stolen from me, called me a "fucking child who dose not know shit.", and uses us to her advantage.
<bot>: My sister has done every crime under the sun. She once agains defies her parents and invited her abusive boyfriend in. But we just can't kick out a pregnant daughter/sister.
