The Greeting Similar to writing letters or meeting someone on the street, the conversation usually begins with a greeting of some sort.
Different greetings convey slightly different emotional tones and levels of intimacy.
In fact, newbie e-mail users often fall back on this familiar way to start off a correspondence. In most cases, it's a bit too polite for the casual atmosphere that many associate with the internet. They might view the sender as being naive about the social dynamics of e-mail. A very handy, all-purpose opener. A more enthusiastic salutation, almost like hugging or slapping the person on the back.
