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 teenager 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 their parents were doing. And I mean gambling addiction in the first place. Kids from such families don't want to even hear about gambling, let alone engage with it.
I guess the saying "to each their own" applies to this scenario as I can relate to both of you as I also don't have such great parents however each family is not the same. While some families' parents will protect and support their children, but some don't and will never want to be just like their parents.
Just as I've said, I can relate to both scenarios as I never want to be with someone just like one of my parents but can consider myself being with one of them. I also, don't have a good parent to have an example to but I'll try to be survived on my own and be someone that I want.
