Me and the wife have been together for 9 years, she was married before and had a son by this chap, right from the time we got together i have always treated him as part of the family.
He is now 18 and since he left school he has turned into a breakless layabout, his excuse is ' i don't know what i want to do for a job' so we suggested that he gets out into the marketplace and tries a few until he finds one that he will like, his answer 'but i don't know what i want to do so i don't know where to start'

He is not the most outgoing person in the world, coupled with the usual teenager attitude, by his own admission he had no practical experience of doing a CV or dealing with interviews, so i have spent a lot of time coaching him on dealing with questions and interviews and putting together CV's and application form.
We finally got him an apprenticeship in the local Audi dealer, i knew the Dealer Principle quite well and pulled a few strings, i figured that once he was in there he would knuckle down and show them that he had commitment :-/ he lasted 5 days and they let him go/sacked him due to his attitude and unwillingness to do what he was told

since then he has dossed, drifted from college course to college course, lied about where he is and made up countless excuses about why he didn't get the job he applied for.
I am away from mon-fri so i don't get to view the situation on a first hand basis, my wife had chronic ME and sometimes she can deal with the aggro, but i decided to 'follow up' on some interviews he has been to recently to try and get some feedback, the response was interesting.
1) can you send an interpreter next time please so we can understand what he was grunting about
2) I have never seen someone sit in a chair.....horizontally!!!
3) He didn't really seem interested, when we asked him why he applied he just shrugged his shoulders and grunted.

So i faced him yesterday with this, now it was fair to say it didn't go down well, i was 'checking up' on him, which i admitted i was doing, his view is that the world owes him a favour, he is collecting it and his intention is not to get a job but to doss on the benefits, at this point it all kicked off in a monumental fashion and we squared up, i had him by the throat against a hot radiator and at that point he saw things from my prospective, either that or he was getting burnt

We have got to the point where he is affecting every single person in the house, we don't speak, my wife is tired of his attitutude/behavoiur and my daughter doesn't like the way he speaks to her (and he can be a spiteful little bas***d) and it does put a strain on our marrage
this weekend has been marred by this, i have decided that he is going to be sent back to his fathers, he has said that if i try this he will run away, so again i am in catch 22
any ideas/suggestions
