Adolescents usually hate the things their parents are doing, and after twenty most men and women lead a lifestyle that is completely different from their parents'.
I think it depends on the kind of parents they had. I never hate what my parents had done when I was an adolescent. In fact, I admire them for their hard work and understanding. I think the only thing teen ager hates about their parents is being strict. But then it can be communicated.
What can I say? You've got great parents then, hard working to support you, and understanding, and that is also the support any teenager needs. After all, they weren't gambling addicts, were they?
But that's just your case. You are lucky, mate. Your parents served as a good example for you. In so many cases I know, kids survived only because they were doing the opposite to what there parents were doing. And I mean gambling addiction in the first place. Kids from such families don't want to even hear about gamling, let alone engage with it.
