It's hilarious, I'm not sure why. See SH's manipulative skill here - someone says the beach in the place she lives looks tit and Sali simultaneously mounts her high horse and plays the victim of an unwarranted attack on her "home". Jeez, Sal, some people don't like sitting on uncomfortable stones and like a sandy beach. It wasn't a personal attack. And Feebs, ever helpful, chips in to roll her eyes rather than to say to her friend, who is being over sensitive, "Sali, you're being over sensitive".
What a weird friendship - encouraging your friend's disproportionate stress rather than trying to help alleviate it.
I wonder if Sali covers this in her book. Maybe a chapter on "Being friends with idiots"
