This thread is inspired by Ivan Seeking's thread styled "Pointing with the middle finger." I notice from time to time that when some people call another person's name, rather than responding with "yes?" or some other type of reply, some people seem to inadvertently commit the act of rudeness by responding "What?". I don't think that the people are deliberately being rude. I think that most of the people don't even know that this is bad manners. Example: John, "Bill." Bill: "What?" Whenever I hear this, I can't help but think "Doesn't that guy know that it is rude to respond with what when someone calls him by name?" When I was in public school, the customary response that a student would make when a teacher called his name to get his attention would be "What?", though nobody ever said anything about it... What do you people think?
