OP asked how to get her sister out of the house in the context of a self-serving tale of how terribly the sister was behaving. She could have avoided the free advice about her familial relationships if she had left out the long story and the complaints about sis. It was nice of her to help her sister. It is within her rights to legally evict the sister. But the sister doesn't seem to be the villian OP wants people to think she is.
So true, las365.
In most posts on most message boards, there is a lot more to the story. We/members just go by what we’re given.
I’m surprised OP didn’t just come here and say “My older sister mucked up her life, can’t keep a job, I let her move in with me, now she’s mad about some silly thing, won’t talk to me, so how do I get her out of my house?” or something to that effect.
No . . . OP gave us a more complete story, and I think she really expected sympathy, Obviously she didn’t get it. I’ll bet sister would have quite a different story to tell.
If I was sis, I'd beg/borrow money from whoever, box up my possessions, say "Thanks, it's been real", and get the heck outta Dodge. Like, NOW.
