My T didn't talk hardly at all during our first four months; s/he took a lot of notes, but other than a few neutral facial expressions, I thought I was talking to a blank slate. Some Ts use early time w/clients to observe and listen to what the client is saying and how they're saying it. Now, six months in, T is talking more, asking questions, making comments to what I say...more normal conversation.

I could be wrong, but it sounds like your T is observing and listening to you. Personally, I like how my therapy has evolved; when T talks, I get the feeling s/he understands where I am and gives feedback that makes sense to me. It may not be something you like or need, however. Let your gut be your guide...
