Earlier quoted context omitted.
I'm extrovert as hell and I like pair programming...but not having "what are we going to do" written down, combined with a constant hum of conversation in the background sounds awful.
To clarify, I'd be fine with pairing 8 hours a day, but I'd want: - Some sort of sound barrier so that I couldn't parse the background conversations. - To be able to decide "what is our current plan?" and to write that down. Of course you'd change to a new plan in light of new information.
Individuals doing solo work are often distracted by background noise, and even I do! But in pairs, it doesn't seem to have quite the same effect in my experience.
On the planning part, I know a lot of pairs that set up small daily roadmaps to stay on track. Totally normal, and also totally ephemeral as well. Usually an updated plan is drawn every day since the pair might change.
