I can see how their philosophy of "First, you have to give up being right, even if you are" can influence things like peace talks. It was one of the things I learned early on in dealing with my father, and sure made my life a lot easier. I didn't say pleasant, but definitely much easier.
Of course, in my case, I think the major reason I like them is simply this: for the first time in 32 years, I didn't get morose, morbid, or depressed on Mother's Day. Here's to letting loose of pedestals, self-blame, rationalizations, coulda/shoulda, and idolizations, and self-blame. In return, I accept better understanding of a remarkable but troubled woman.
