Pair Programming "Out Loud"

One element of Pair Programming that I find key to success is "Programming Out Loud". When I have the keyboard and mouse (driving), I want to be explaining my train of thought to my pair partner, moment-by-moment. Conversely, if I am the non-keyboard partner (navigating), I want my partner to be explaining their thoughts moment-to-moment. If my partner is practicing "silent pair programming", I try to ask ask questions like: "What's next?" or "Where are we headed?" to try to get them talking about what they are thinking or doing. Or if that doesn't help, I can ask to drive for a while and try and draw out their ideas that way. Usually things don't go this far, unless my partner is new to pairing. When I start to go off silent and solo, my partner usually invites me back into collaborative mode.

But what if my partner is the navigator and they are disengaged? I can ask (slightly tongue-in-cheek): "Are you with me?" It can require courage to "call out" my partner in that way, but sometimes it takes courage to be on a successful agile team. And if I'm the disengaged navigator and I catch myself being distracted, I can ask to write the next test to try and focus myself back on what we are doing.

Do you have ways that you draw a distracted partner back into collaboration? Or do you have ways to get yourself back into collaboration?
