Now I am so curious (genuinely!).... how would one know how the therapist is with other clients? My therapist doesn't say much about any of her other clients or how they feel about her or anything really, other than an occasional "I had a client who (general non-identifying story that's related to what we're discussing)..."

I am a little idly curious about others because I am curious about people in general, but then I think...I wouldn't welcome their curiosity about me and my sessions.
