You make an important point, Aus, that I missed in my eagerness to share.
Was Linehan advising family members and significant others to try this? Or was she advising therapists?
She was speaking to therapists. There are some skilled colleagues I have who can do it, but it is admittedly really hard. Sigh, I wish I chose a different career recently!

In any event, I looked back at my notes from her speech at the conference, and some quotes that I wrote down:
"We process more deeply information that is not expected."
"Irreverence is not a style... .it is a method of behavior change."
":)istraction is one of the most effective emotion regulation strategies."
