I agree that her lack of friends in the industry (and in general) is telling. Not that not having friends is bad, but in Carrie's case I do wonder how she spent all those years at Les Mis without forming any meaningful friend/relationships with the dozens of performers she must have shared the dressing room and stage with. She has been in quite a few shows and I never got the feeling that there was a cast that particularly liked her. Maybe she's super awkward, or maybe she's just as judgmental and entitled as her online persona suggests. Plus, she has NO real love for musical theatre just for what SHE gets out of it (applause and fame).
And again, the disclaimer: this is not a dig at people without friends in general, just at Her Royal Highness Queen "I literally Carrie Hope" Fletcher
