Hi Mike and Mark,
I'ver been told that I often roll my eyes and scrunch my forehead when I don't agree with something that someone says in a meeting. It doesn't help that I'm following your tip on always turning my body towards them to listen. It's something that I've done all my life and have no idea how to stop. I've asked my wife to speak up when I do it at home, but in the work place, I don't have any one I can trust to give me the feedback count after a meeting.
