Baby T is as close as I've ever had to blank slate. He talks minimally about himself (at my request), he isn't very reassuring about anything, there is no outside contact.
However he TRIES to joke around a bit, or praise me (he knows I don't like it and says that each time), and he is "familiar" now I guess but I have no attachment. I don't feel any need or desire to talk to or see him outside session, I am fine with breaks. I am ok with this sort of T because it keeps me from getting into the "relationship" aspect too much.

Very first session when he was a stranger (along with 2 other Ts) I basically just started talking about personal stuff. I didn't want "time" to build trust or anything. I just wanted to talk and limit their talking time. It seems to work for me this time, although baby T's inexperience is showing now but that's a whole different story
