The joke, a favorite of small children I know, goes like this:
And I've been thinking about that as I continue my international disciplinary workshop / gender theatre 101. I have noticed a woman interrupting a man precisely once in discussion. Every woman, including me, has been interrupted by men multiple times. Last week, a male participant interrupted a female participant about three times in as many minutes, insisting that she wasn't answering his question. Of course she wasn't answering. She was supposed to have the floor, and couldn't get a word in edgewise. Yesterday, the female presenter, when answering a question, was interrupted by a male participant who started his comment with, "I demand that you fix this."
Don't be an interrupting cow. Shut up. Listen.
