I'm going to kick a lady out of my post at night
Why would you wait until night? Couldn't have done that sooner?
Yes, I should have directly kicked her out first.
You should respect other peoples opinions. It is wrong to kick someone out after you have previously let them in before without an excuse.
Okay I agree, what if then I just tell her she is not allowed to sleep there.
That's a great idea and a perfectly reasonable assertion. She may be upset, but at least you're going about it the right way.
