I think my therapist's mind could wander, because she is human but I don't think it happens often. She is always very attentive. Sometimes she is quieter. Sometimes I am quieter. Sometimes she is tired. Sometimes I am tired.

There were times early in therapy that she would get this certain look, a severe and (to me at that time) angry look. When I brought it up once when she was doing it, she instantly relaxed and chuckled and said "I know exactly what look you mean. I know that about myself, that I get that look when I am thinking." So I know now that this look is when she is connecting something important, something happening in therapy with something from her experience, training, education, etc.
