email etiquette`

I don't even know if I spelled the word right - etiquette. Anyway, I am not going to let it go! I will be the last dinosaur on Earth and start emails with a "Dear" or a first name, and close it with regards. Or something. Anything.
I resent getting responses on a professional level from strangers, using one line short sentences more similar to text messaging. Are we this busy? Are we really? Because to type, it takes a lot less time than finding letters on the phone, and including three more words and two extra lines CANNOT possibly take up enough time to justify its omission. Exclamation point. Twice.
Geez! I would like to be addressed when spoken to, and dismissed with even a "New York haveaniceday"
When I see movies and how they just hang up, and doesn't say enough words on the phone to convey the camera's action and facial expressions I think: how rude! Softly placing a receiver down with gazing eyes conveys absolutely nothing to the other end. Hello!!!!???Can't see ya!

I think we should be extra careful and communicative when writing. Make the extra lines, say the extra words, even if its automatic. One has to see and read them. It would be helpful if colleges focused more on actual creative writing instead of the tedious and STUPID research papers. What's that all about anyway? Gosh, don't get me started!
"Hello, young adults, this course's objective, for which you have paid )*^&^%&* dollars, is to teach you how to use google and a spell checker. No independent thoughts need be expressed. But you must site 20 references in the bibliography, and use APA style properly..." Greeeeeeeeat...just so you can sit in your high paying corporate chair and write two line emails that, when read aloud, actually sound rude and primitive.

Please, insert the niceties to strangers and business correspondence.
Thank you!

Best regards,
