• By overdoing it in the "helpful" category. The things they normally ask you to do...start doing them without being told.
• Ask for more chores.
• Ask for advice on more things
  • "Mom, how do I know good boys from bad ones?"
  • "Dad, what are some good character traits to look for in teenage boys?"
  • "How can I tell when someone is being sincere? Guys or girls?"
  • "I know I've done some things wrong in the past and I want to thank you guys for holding me accountable. I can see now how that's better for me in the long run."
• Trust your parents more, demonstrate it by letting them in on some of the thoughts you struggle with that you normally would only share with a friend.

That last one might not work well at first, but do it anyway. Once your parents are used to the idea of talking about things with you openly (they need to get over the shock and the topics), then their input will be most helpful. Truly. But it will take some time.

Trust from parents isn't the same thing as "permission." I trusted my kids, for the most part, but the world is unpredictable and protecting them wasn't optional. So, I still played the bad guy and didn't let them do everything they wanted....it comes with the 'parent' job.

That means you need to demonstrate some understanding of what they face as parents, too. They can't/won't/aren't supposed to agree with you about everything because even if you're right, they're still responsible, and that's a hard burden for parents to bear. You need to keep that in mind.
