Over the 2-3 years in therapy my T has told me a few general details about herself, only in relation to my own experience.

I know a little bit about her marital history, a little about what her Dad does for a living, and that she has 'kids' at least one of them being a daughter.

Thaaaaaat's about it.

It frustrates me that I don't really know much about her, her interests, her own likes or dislikes, hobbies, anything... personal at all, really. However, I get why this is and I appreciate the purpose.
