And that is a comforting thought.
To me, Piper seems to have more perceptive powers concerning how to handle herself in front of the cameras than her older siblings. She is certainly not in awe of them nor intimidated by them.
She has to have seen TV reports of her and her family and perhaps even ugly ones. It does not seem to have caused to be sullied by it all. In fact she seems to be as natural as ever, and totally uncaring WHAT the press thinks about her.
So maybe she does have a more assertive, less submissive air about her than a lot of females her age or older. I see that as a positive, self-confient character trait, rather than a bratty one.
