I think it is basically because they set out with the intent of BEING RIGHT, verses just "being."
if each can just "BE" then we are free to go for it in communication and life, and have fun, get excited, apologize, accept apologies, and so forth.
for me personally, i am so prepared to "BE" that i will even apologize and get on down the road, whether I am right or wrong.
IT IS OK FOR ME TO BE EMBARRASSED BY ME! good thing to, cuz it happens often- LOL!!
When I have an arrogant self righteous moment it almost walways feels yucky.
