I agree that we should keep our standards of professionalism top priority, but what happens when instructors get too authoritative. When I hear some instructors disciplining students it sounds like the beginning in that Twisted Sister video...tuck in that shirt, stand up straight, wipe that smile from your face, who are you, where do you come from, are you listening to me?, what do you want to do with your life... How do you get through to those guys that this isn't high school and most of our students will respond when talked to.
