Yes, yes, yes! And, we are all probably developing mental images of those 'special' people who we've had to suffer through in class. I used to work for this company that required weekly meetings. We had this guy that would turn a 15 minute meeting into an hour with 45 minutes of stupid questions. I finally suggested that all questions should wait until the meeting concluded so the rest of us could split. Suddenly, the guy had no questions when he had no audience.
