What do people love more than getting email?

I need to learn how to program an application.  I have a great idea for an email client.  What do people love more than receiving email?  Receiving regular mail!  Yes, I'm talking letters that people write with their hands on a piece of paper.  I want to combine those two.  An email program that shows emails like their letters!  The inbox would be a mailbox, obviously, and you could check the mail whenever you wanted.  The animated mailbox would open, and you would get you emails.  You could open each "letter" by opening the envelope, and unfolding the piece of paper the message would be written on.  When sending an email you could choose the envelope you wish to slip your letter (written on personalized stationary, of course) into.  Then, you pop in into your mailbox - now functioning as the outbox - and the plastic flag would pop up.  Then, well the email was sent, the flag would go down, maybe a little mail truck would drive by too, I don't know.  You may be asking "Well, were are the letters that I already read stored for later reference?"  You probably weren't thinking that, but I made you think it didn't I?  Hahaha...  Anyway, all letters that have been previously viewed would be stored in the "Read" box.  By box, I mean a little plastic thing that holds all the letters.  The file system of my program is born!!  When you find the need to, you can insert a divider into the box, creating more specific boxes.  C'mon, all of you would download this program if I made it.  So, if by any random chance you can program such an application, or you know someone who could, or know someone who might know someone who possibly knows somebody who hypothetically knows a person who could know a guy/gal that could program an application like these, I'll be here.

My idea, don't take it.
