She behaves as if she is a millionaire. She claims to have lived in a specifically wealthy area until her house burnt down.
The way she speaks and acts, if you are upper class or know people who are, it is clear Carla is nobody living in a fantasy.
Those who don’t know her are lured into assumptions which she provokes.
Although not yet forty, she was akin to a spinster of seventy, a hoarder, surrounded by her cats.
If you are in proximity she will speak of her family and connections, usurping famous names. But she is so crass that how long she can fool people is truncated.
Carla lives in a closet of her own creation.
