Do you accept everything that your parents say at face value without reservations or doubts?
Yes, as a matter of fact, I did. I trusted by parents to raise me the right way. Must have worked, as I haven't killed anyone. Well, lately.
Seriously, tho. When my children come to me and ask me the why's, the theory behind it (not why am I being punished, but why is it wrong to do x) then I know they're ready to leave. For myself, when I was about 15, I started realizing why thing were the way they were. I was ready to move out then. Of course, I had a good thing leeching off of my parents, and managed to stick around a few more years. My kids will have until they're 18 and graduated, then out they go. Unless they're doing college or something else, and need a couple of extra months. Hey, I can be generous!
I fully expect that soon I won't be correcting them at much. As it is now, the 11 year old is doing much better (as far as corrections) than even a year ago. He's still got a ways to go, but he's getting there. He's not questioning me yet. . . but he's getting there.
I really wish I could say this better. I know exactly what I'm thinking in my head. Putting it in a post is much more difficult.
