You brought up communication style; I wonder why?

I recently attended a virtual training session at my company on DISC. The idea is that if you know your own style of communicating and the styles of your closest coworkers, we might get along better.

I'm mostly C and S; my boss, D. My most recent 1:1 left me in shock. Like you I thought I was highly productive. But he complained about lack of progress on one project that he gave poor direction on, and about another task that I did that was based on info he failed to update me on. I called him out on this and pushed back hard and said he needed to communicate better.

But still, I felt awful for a couple of weeks after that.
