Maybe I should clarify.
The way Pippa has been treated by the media (which is what this topic is about) may be the reason she MIGHT shy away from immersing herself into the fold. As she now knows, any step she takes sends the media into a frenzy and her life is turned upside down, traumatized by her personal life at the front of media gossip, the way she walks to work, what she buys in her groceries and she's not even a royal - so with those points in mind, I wouldn't blame her if she took relaxed approach to the RF.
Afterall, she doesn't have to be seen visiting her sister, so she probably does see her quite a bit, we don't know. But if every time she did pay a visit and it was reported in the media, then whew, I'd be a bit relaxed too!
I feel it's a catch twenty-two.
