My two who've left school don't seem to have any ambition. !7 yr old always said he wanted to be a chef, but is working as a kitchen hand in a pub. I think in a similar way to the "X factor" wannabe's, he thinks he'll be discovered by MasterChef one day while putting chips in the pub fryer. The fact that he can't cook to save his life doesn't seem to worry him too much.
He has no friends or social life and spends all his spare time playing x box. He spends his wages mostly on sweets.
The 19 year old flunked his a levels cos he didn't do any revision. He was in a band and they were very good. His band members then all buggered off to Uni and left him twiddling his thumbs. He's gone back to college to do a two year course, but clearly isn't putting in the required amount of effort. Completely different to his brother, he spends most of his time (and money) on his party lifestyle and is rarely at home, we've had to take his key off him because he takes every opportunity to have wild parties where the police have been called when we've been away.
Neither of them help out at home, and they don't contribute financially but then their main home is at their mum's house anyway, though she doesn't charge them board either.
I dread to think what would happen to these boys if they had to fend for themselves, I don't think they could TBH. I'm trying to bring my son up at bit differently, he already does quite a few chores and already knows that he'll be expected to contribute financially once he's left education.
