My old T want exactly a blank slate. But didn't self disclose much at all. I remember asking a question regarding her relationship with her mother and she did her normal gentle smile as a response. I remember saying to her "how can I understand me if I don't understand you!?". With that she thought and then said "no I didn't get on with my mother". I thought that might lead to more self disclosures, but it didn't. She was like an elastic band. She'd stretch then go back.
