Thanks for your thoughtful post! It's amazing how people go for the knee-jerk reactions: Kick 'em out! Make 'em pay rent! Drive them to a recruiting office!
Sorry, I was assuming the op has already went that route. I donot consider the above "knee jerk" reactions. My job is to be a parent, one thing my responsibility is to teach my almost adult kids their responsibilities. No matter what the age actions come with consequences. Whether on the job, in school or at home. No body gets to "do what they want".
Sorry I agree with the majority. If my children feel they are adult enough to continuously disregard the house rules and disrespect me and the other members in the house, then they are adult enough to face the consequences.
Then we wonder "what's wrong with kids today"? kids today did not just spout up out of the ground, ill mannered and out of control. They were
allowed to become like that, they learned that behaviour was acceptable.
Whether they are 8 or 18 I will not allow you to run amok without consequences. I will not be an enabler.
I tried that stunt when I was 22. I graduated from college, moved back in with my parents and thought since I was an "adult" I could do what I wanted, Had guys in my room all hours of the night, came home drunk, partied the final straw was when my grandmother died, I show up at the funeral in a white miniskirt looking like some saturday night hooker. my parents had had enough. I came home from work one day and found all my crap in plastic garbage bags in the front lawn and the locks changed. Better believe I got my act together quick fast and in a hurry
