November 20th, 2008 - Bad manners
I was on a panel of four people yesterday. We were all told to speak for 10-12 minutes; one person spoke for 25. It was the second time I have been on a panel with this person over the past two months, and he did the same thing both times.
Small slippages in time happen to us all–very often the pace of our speaking changes with venue. But someone who takes up more than double his allocated time is either unprepared or inconsiderate–probably both.
