No the person you've replied to, but for me I just find it frustrating. When I'm not the one typing, I always find the other person moving slower than I can think, not entirely getting what I want to tell them ("no, line 47, not 53 -- no, the foobar function call isn't the problem, it's the 4th argument to barbaz... no no, no that one... GAH). Maybe we can chalk this up to "communication problems", and I should have taken a pause to talk about communication with my pair partner.

I dunno. I've just always felt much less productive with someone else there. I don't view programming as a social or collaborative activity. Building software can be collaborative, but when I'm sitting down to do implementation, collaboration slows me down, and I find it very frustrating and unproductive.
