My cousin is an asst psych professor. Her new boss brought up how male students sometimes challenge female professors. He asked how she handles that: she says ‘hold on: let me take notes’, grabs a pen & paper, and proceeds to take no notes. If he asks why, she says ‘Tell me something I don’t know & I’ll have something to write’; no student has tried twice. Her boss laughed and asked her to mention it at the next staff meeting.
