Well, it's been helpful to us for a few years. Unlike in the Seinfeld episode, NVC isn't about "bottling up" or keeping your emotions to yourself. It is explicitly the opposite: all about communicating unmet needs and finding shared understanding.
I think both of us would say that we feel we have a better understanding of each other and a much stronger relationship as a result of NVC. YMMV of course!
in my quest to better understand your position, I once again believe you missed the point. I think you are suggesting that NVC is artificial and smooths over chaos that needs to be experienced else things go worse later. NVC is expressly about not repressing your feelings and letting them be known via your unmet needs. Again, if I got this wrong, you are invited to correct me.
Mostly I'm just bored between meetings and not enough time to push anything productive forward and having a back and forth is pleasantly distracting. Might not reply again since work is nearly beckoning.
