What age did you realize your narcissistic parent/s were hypocrites, and when did you start rebelling because of that?

On the whole, my parents are neither narcissistic, nor hypocritical. But they're not without their moments, either. And for the most part, I was a pretty well-behaved and eager to please child in contrast to my sister who was the rebellious one until she started becoming a mother. I didn't develop a rebellious streak until I was 17 and even then it was only slight.
