The first time that I started staring out the window and all I could say was "I don't know" to all of T's questions, T asked me (the next session) what she could do to help pull me out of that. We talked about it for a while and decided that T giving me choices of possible answers is the best. She will usually give me 4 or 5 choices, and then by that time, I have come back and can either tell her one of her choices was correct or tell her what the real answer is. She also knows that if I don't say anything at all, that means I need her to rephrase the question.
