thanks for coming

So... gave a seminar to my colleagues today. they looked interested and seemed to enjoy it. Except for the bossman whose question at the end seemed to imply that the topic was one that is outside my area, which was a bit rich since he knows nothing about my area. Then my colleague stood up and gave his seminar, adn the bossman sked exactlyt he same thing. To me, the interpretation of the question that we had to surpress was 'so what?'. Since he is not involved in our area of research and didn't really engage with the content of the our seminars, what right has he tell us what is appropriate or not! Thanks for coming....
