I was going to mention the same thing. My younger brother went/is going through the same phase, though now he is in college. I also believe it resulted from not having good role models in his life at that time. My parents have stressed significantly over this, and their efforts to make him into more the person they want him to be drove him further away. Personally I feel that you as his father will not be able to directly change him because until he is 21(ish) he will rebel against most of the things you say. The best course to influence him is to insure that he is spending time with the right people. I agree that he will need a job soon, to pay for vehicle/insurance. If he doesn't want one, then consider asking him to begin saving money for higher education or even to pay for a small portion of his rent at home. When looking for jobs, make sure his first is one that will work him hard and teach a strong work ethic. Success at a hard job should bolster self confidence and make him appreciate his free time more. I would also say not to be discouraged... These must be the hardest parenting years (in my opinion)! I had serious issues with my parents during that phase of my life, but a few years later I realize that they were right on almost all counts. Good luck Oleg!
