My guess is that this conversation happened entirely in his head. His wife was in the room nodding and mumbling "uh huh" while he rattled off hacker-speak for way too long. He left off his wife's last line of: "Sorry, did you say something?"
That's his fault, not hers. You should see her version.
When I write conversations down it's hard to capture the spirit of the give and take. My straight-line write-down-the-meat approach always ends up devaluing the questions and ideas raised by others. My goal is to record what I learned from them, and I often come off sounding self-obsessed. I think it's an occupational hazard: all of us emphasize what we say in our own minds. Writing down conversations just uncomfortably highlights that fact.
