I am about to have a chat with you here about conversation habits, which to some people, is a highly sensitive subject. We are seeing more bad habits in the public, and this can in part come from the kind of training wrought in the home. From business to politics, little restraint is practiced by some people. Yes, right now, it is only a few people who are at fault, but rudeness can become epidemic if it is not noted and self-corrected. Like disease, bad habits are easily caught and spread. Young people who are well brought-up may enter the public sphere and be influenced to adopt some of these bad conversational habits that make life depressing.
