Same. It seems the coding part of my brain and the communicating are mutually exclusive

I wonder if it’s related to the phenomena of some people having a ‘narrator’ in their head or, like me, there’s no voice and it takes effort to convert abstract thoughts to sentences

no I have the voice but I can either explain or do, not both.

Maybe this is a misconception or misrepresentation of pair-programming, at least compared to my experience. One person isn't supposed to be doing both. You're either navigating/explaining or driving/doing. Pair programming isn't about one person doing everything and another person watching and trying to keep up. It's about communicating and sharing an understanding, like a realtime/interactive PR description/review while writing. Of course there are times where one person will simply say "let me write this out and discuss after" and go at it for a short while, but it should be the exception rather than the rule in settings where it worked best for me.
