You mean the twin thing? Same logic tho. Perhaps her parents always put her twin sister first and she was the golden child. Sibling dynamics can be sickenly complicated and, yes, traumatizing. She is not talking about her zodiac sign as far as I can tell. And I mean yes it is probably a joke, but at the same time it might be very pragmatic if you are in therapy anyway. Instead if telling something over and over just tell about the progress you made with a previous professional in a presentation (so that also you don’t forget something important)
