I'm not sure whether I need advice, or just to vent, but I'm troubled by my little brother at the moment. He's actually my half brother, he's 17, in college and lives with my dad and his mum. Lately he seems to have gone off the rails a little. He quit his college course last year because he didn't like it and started a new one a couple of months ago, but it doesn't seem to be going well, as he's consistently late and often misses lessons. I don't think he's going to last much longer tbh. If he does quit, I doubt very much that he's going to want to find a job, which worries me because I want him to have a great future and he can't do that by sponging off his parents. He's recently started taking driving lessons, but whenever my dad takes him out, he'll start speeding and just doesn't listen when my dad tells him not to. It worries me as he doesn't seem to appreciate the fact that he can't possibly pass his test this way (as well as it being dangerous and illegal) and, at 17, he should understand that you have to follow the rules; just because you want to drive faster, doesn't make it right. Recently he's been spending a lot of time with a female friend who has a serious boyfriend. The bf has already made it clear that he doesn't approve of the friendship and does not want my brother at his house, yet every day after college, by brother's there until the bf comes home from work. He's also becoming difficult at home, arguing with his parents and basically showing no respect (I think he has unrealistic impressions of the cost of living and assumes that he could leave home tomorrow and find a home and a job, without any real qualifications or experience). I suppose I'm just concerned about the person he's turning into; he doesn't respect authority, doesn't seem to be concerned about providing for his future and is putting himself in an awkward position with his friends relationship. I'm the person he comes to with the things he can't speak to his parents about, but I'm just don't know what to tell him at the moment. I'd really appreciate any thoughts.
