Grifting has highlighted the worse of Fanny’s narc traits, but it's just not Fanny's money hungry, dishonest lifestyle that has caused old friends to distance themselves. We never see Fanny taking time out of her trips to meet up with old friends for a drink or dinner. What does Fanny do to stay in touch with old friends - NOTHING! It's all about her and not about them.
Fanny is a transactional phony! Can you mail Fanny a box of her shopping and pretend it's a cadeaux gift. Can you babysit Fanny's shitoo while she's on vacation. Can you come for the weekend, it's going to be a fabulous party plus I've got a costume for you, and it would be wonderful if you would cook your delicious roast dinner on Saturday evening - they'll be 16 of us! People get tired of being used, especially when Fanny is making money off of your efforts by filming it for YT !
Unlike Fanny, most of her old friends have grown-up and now have real lives, real jobs, real families and real responsibilities. They don't have time to travel to the middle no where in Central France to play dress-up and make believe. Even if they are still interested in coming to an annual, silly dress-up party at the dump, they don't want a pink camera stuck in their face filming the entire weekend and then have it posted on YT.
For the first time in her life Fanny had friends at uni and that's where she peaked in life and got stuck! Staying at the dump was fine when they were all young, drunk, silly and stoned. It's not as much fun when you are middle-aged, drunk, silly and not stoned. Her friends standards have gone up a bit, but Fanny doesn't seem to have gotten that message when it comes to entertaining her own guests. Fanny loves 5 star, but she treats her guests like they're still 21 year old students staying in a 1 star, no-tell motel.
Even many new chateau friends, unless they are desperate (ie: the Shreks, Permasmiles) only visit the HMN once, out of politeness, and never return.
Finally, who the hell wants to spend their time hanging out with Snorty? No one with half a brain. Snorty, the closeted gay, pre-pubescent drop-out brings nothing to the table and Fanny's bogus boyfriend shtick has contributed to making her a laughing stock!
