Crazy-ass bag lady
I don't care if they are derived from what passes for aristocracy in the U.S. There's nothing from little Edie that you don't see from thousands of homeless nuts on the streets of NY every day. At least her mother had some small modicum of talent for her day; little Edie had nothing going for her but delusions.
I don't understand why anyone gave her the time of day. Go interview some schizo bums on the street and you'll get at least as interesting (and likely more sanitary) an experience.
