Agree on most points about Roxann. She didn't seem like a true hoarder, so long as she can keep it under control. And she didn't really have that much fabric, if that was really all she had. The boyfriend was kind of a jerk, especially telling her to get rid of her kitchen chairs. The point of the cleanup isn't to leave the house bare. If that was her only kitchen table and chairs, then I see no reason not to keep them. They may have been old, but weren't part of the clutter. If he hated them that much, he could have offered to replace them with something newer.
Barbara was a sad case. I have a feeling she may eventually get things done, if they take a different slower approach. She was deep in grief and seemed totally overwhelmed. Clearly her hoarding didn't happen overnight, but I think if her family continues to support her and slowly go through things, I think she might get rid of them. But they will have to constantly reassure her that they care, and she needs a lot of support. Without that, she won't get any better.
I wonder if her younger son feels some guilt for starting the fire that changed her. I hope he doesn't carry that burden with him. He didn't seem to.
