Quote #10
"This is all very funny," Schwinn said, meaning it wasn't. "Now, if you're all done—"
"Done? […] Lady, some of us have been here eight or ten years and we're never getting 'done.' We're just graduating. I mean, that's our point, if you haven't gotten that yet. We need the group to get by, but we ain't getting better." (25.59-60)
Karl about sums it up here. It's the social relationships within the group, not the group itself, that helps them "get by." The fact that there's a therapist facilitating the thing is purely incidental.
