Oh, man, I sort of felt I had the opposite problem with my T. Mine didn't seem "able" to understand as many points of view or arguments as I felt I could and she wan't a native English speaker, etc. I just used that whole interpretation of mine and worked to learn to say things in a more simple, straightforward manner than is my wont

I figured I would come across people like my T in real life and being able to commuicate with them would be just as important as communicating with those like myself. Were I you, Echoes, I'd use your T's presence to practice shutting out her personality and dealing with the distraction of it for the same reason that you might meet and have to deal with others like her?

If you enjoy some of her personality, try to copy it? I know I'm much better now at stopping and thinking what I want to say and how to say it straight out (when I recognize and think to do so) with all my words in place so the other person doesn't have as much work to understand me because I wanted my T to understand. Maybe you can practice saying what you feel faster, without thinking it out (being more spontaneous?) and trusting yourself more, because your T trusts herself?
