And to be spitting mad that he a) refuses to do so and b) then complain that I do nothing around the house. 
I told him his room was a pigsty - at which point he told me that I was a pig and did nothing around the house anyway.
I told him that "nothing" included doing all the washing, stacking and unstacking the dishwasher, nagging him to empty the recycling bin , all the evening meals (from scratch
), changing the bedlinen, 95% of the ironing (his dad occasionally has to iron his school trousers and jumper as they're not dry by Sunday night 'cos I've had to nag him to get the dirty washing into the washbasket ), act as a taxi driver for him to get to cycling and rugby training.... This at the same time as looking for a job (we've been living comfortably off redundancy money for a while) and helping dh as he also looks for work/tries to set up a business.
I told him that if his attitude was that he didn't need to do anything and that if he though I did "nothing", I would go "on strike" as far as doing things for him was concerned. He claimed he didn't need me to cook for him as he can cook now (after his Home Ec classes).
I then told him to get out before I said something I really regretted - and that if he was so good at cooking, I would leave out the chicken noodle soup that had been in the fridge and he could heat it up himself.
How can I get him to understand that with rights come responsibilities (he keeps on threatening to call Child Line)? He is an intelligent boy who is in his 1st year of secondary and to everyone else is a charming boy I know that's a common "complaint" with teenagers/proto-teenagers 
The argument started with me trying to warn him that his dad was at the point of going to his room and scooping everything into black bags and that unless he did something about it, it was going to happen. He was warned in January that if it wasn't tidied properly by the end of March that dh was going to do this. I told him I was fed up of trying to help him by doing some tidying for him - but of going back into his room a couple of days it is worse than ever: clothes all over the floor, books, pens and toys all over the floor and surfaces, all the drawers wide open.
Help!
