And a 15 second conversation couldn't be dragged out to a fifteen minute exchange of texts, you wouldn't have that exited wait, wonder if your message had been received, if it had been read and if they'd already sent a reply and you just hadn't received that?
To further enhance this experience I was thinking......instead of typing texts, we could write them, maybe on a rolled up piece of paper, and give it to a man with a horse to carry to the intended recipient.
I was thinking of patenting this idea but I'm not sure that it's an entirely new concept
