I saw an interesting article ACRlog, which asks the question: Does it seem like the traditional (18-22) students showing up at your college or university are behaving more rudely than past generations of students?
The answer is complicqted. Scientists insist that today's students living in a technology dominated world, with social lives that are revealed online, has a different concept of privacy and personal boundaries. Making a good impression means far less to them. Exhibiting rude behavior, such as listening to an mp3 player or playing a video game while others are present, is thought to be part of living in a technology bubble.
