It's infuriating when you are simply trying to get something done and the other person is more concerned with the alignment of their spoken words than actually giving you the information you need. Just tell me what I did wrong so I can fix it ffs.
But, when people are taking on things like this at first, it is awkward. I remember my first one-on-ones as a manager were super awkward, because I hadn't internalized a sincere way of doing it, I was following a recipe I learned on a podcast. And, for someone to learn to be a good manager, there's likely to be some awkward recipe-following along the way. We're all learning as we go.
I think for things like NVC there's the stated technique, and then there's the art of it. The art takes a pretty major shift in mindset for a lot of people, and managers can still be in very high-level roles while still being super insincere robots, usually because they're really good at other stuff.
My natural voice? Is that my violent one?
