The older generation generally had more difficult parents and more social demands. They are better at having conversations with people and they also know how to wait patiently.
The new generation is from the electronic age. They want everything now. They don't like to wait and become impatient. Also communication person-to-person is fading. They use texting, facebook, tweeting, etc. They are typically unaware of the art of speech and most of them have what I like to call an orange personality. They enjoy partying and being with other people more than remaining in school.
