That's part of it....although the therapist has very little involvement in the process. It's more like people then respond to the person responding to the person....LOL.

So,

A shares something in group.
B, C & D respond to that person, sharing what they're feeling, whatever judgments they're making, how they react, whatever.
E & F sit there quietly not saying anything.
C then tells B how they felt about B's feedback to A.
E chimes in and tells C how they felt about their reaction to B.
...so on and so forth...

...Often times, the issue that A presented in the first place is lost as the focus turns to what is going on in the relationships within the room at that moment which is the primary purpose of this kind of group. So, I often feel resentment about my willingness to be vulnerable and share in group because it, at times, just serves as a conversation starter so that the rest of the group can do their work.
