Complete tangent here but I've noticed a form of impedance matching when I talk to certain people. I think it's a combination of natural cadence and information density or something, but there are some folks that I can effortlessly talk to and others where we constantly struggle with stepping on top of each other and/or seek clarification. It's a pairwise thing without a common cause that I can see. For example, I can see the folks that I struggle to talk with speak effortlessly with others as well. It's really odd.

But anyway to drive the point home I started calling it an impedance mismatch which makes sense to some and not others. :)
