This extraordinary 'conversation' between a voter and Anthony Wiener, a New York City mayoral candidate, is making me think again about one of the most basic rules of turn-taking, namely: 'one speaker speaks at a time'*.
New Yorkers may of course be an exception that proves the rule.
But, as I lack the transcription skills of the late Gail Jefferson, my chances of demonstrating that it's merely an extreme case of 'overlap competition'**, in which they were actually closely orientating to what each other said on a turn-by-turn basis, are minimal.
