Blood

Writing in blood must be the ultimate. Supplies are limited so the words you choose are that much more important. There is no more meaningful form of communication than a handwritten letter written in blood on a slice of paper made from bamboo or leaves or something. The thought and feelings and meaning are all expressed by the media we use to communicate. A text message is worth less than a phone call, which isn't as good as a typed letter. Handwritten letters are on another level, and when you put blood on that bad boy and make your own paper it gets serious.

That's it, I'm fed up with substandard forms of communication. From now on I'll only respond to sticks and leaves with blood on them. You can send it as an attachment in an email if you want.
