I know he has been in therapy because he would not have a licence to practice if he didn't. He's acknowledged that he has been through therapy himself - and said that he doesn't think anybody could be a good therapist if they hadn't - but I know nothing about any issues, past or present. I don't read other people well at all, and T seems very calm, stable and unchanging to me. I would not want to know, either. Not because I'd want to take care of T, because I wouldn't, but because I would feel even more guilty for wasting his time with my minor non-issues when he had more important things going on in his own life.

So for me it is a very good thing indeed to have a blank slate-ish T.
