Concur absolutely that it is an incredibly important development, but I think my POV of why it is differs rather radically from yours.
For you, it was incredible (or so it "reads" from the follow-on posts) because it opened a window into what W has been going through.
Agree.
I think my sense of its incredibilitude has to do with the fact that W told you.
Why?
Because you don't tell people about your secret hurts unless you trust them.
And trust is a positive emotional-affective response to another; which is an opening; which could lead to more trust and more positive emotional-affective responses; and the next thing you know it's like a shampoo commercial...and so on and so on.
