Now the irony here is he retired from the army. It surprises many people that he knows so much about the Navy, let alone how to do the pipes. For me its a normal sound that I hear when I have been on ship or in some of the buildings at work for that matter. We'll have to see how it goes. It should be less offensive than being yelled at or whistled at ( like the presenter at a seminar I went to yesterday.) Man, that was bad. Considering the room was mostly military, all he needed to do was called ROOM in a forceful voice. Folks would have stopped and come to attention.
