OK so long story short, in the two years my brother has been away at college he has become an arrogant, self-loving doucher. Don't get me wrong, I still love him and he's a really good guy fundamentally, but I honestly have no idea how to get him to be a little more humble and easier to be around. The other day he told me about how much everyone at his school loves him and how popular he is then told me to shut up when I told him I'm starting to teach drum lessons, and that nobody cares. He never used to be like this when he was living at home. I'm afraid if he continues this he'll end up being Charlie Sheen or something like that, and I don't want that because he's my brother.
K+ for good, mature advice
