I'm not supporting you at all. The 18+ should apply to everyone equally and you have gone around that rule. That is not a good thing.
What I'm also saying is that you should not give any ideas to anyone. You got away with it, allright, cant change that. Others should not do what you did, no matter where you live. Your parents were uninformed unless they watch you at all times when you use the equipment that legally belongs to them.
