You know, I feel for Pippa. It must be INCREDIBLY weird to have become famous first because of who your sister was dating; then because of who your sister was engaged to; then because of what your bum looked like at the wedding; and then suddenly have the tables turn. Obviously she is responsible for her own mistakes — no one forced her to write that party-planning book, nor hang out with that douchelord in France who made the gun gesture at a paparazzo — but the entire thing must be bizarre. It probably feels like, “We loved your butt, but WE HATE YOUR BRAIN,” which would be upsetting even to the calmest of people. Having said all that… this is not a wise choice, and her brain may need to take a nap.
