Two humans in complete compliance with the rules of human behavior greeted each other and had a conversation about absolutely nothing relevant that would, in no particular way whatsoever, affect their lives or the universe. In their minds, they both thought they were better than the other while continuously talking and trying to inflict their mindset so as to affect the mindset of the other, always silently rejecting what was coming from the other person unless it complied with their own understanding of their conception of things in this world. They reacted in accordance to the arguments put forth by the other, smiling, agreeing or opposing when the message communicated obviously needed opposing, until, they finally parted. They waved their goodbyes in the natural order of goodbyes and agreed to meet once again to do exactly the same thing all over again.
