Just a few quick notes that I'll expand on later

• Perspective. My perspective is an outside one of everyone else, so how do I know you're real? You can tell me you are, but my brain would create characters to do so, thus making everything possibly fake. 
  Same goes for you. This may just be a creation of your imagination, and there's no way of knowing because I would tell you so. Persona creation.
• Present. The past is irrelevant. Right now, all the time leading up to right now, only took a second in the present. Which is always. It is always the present. Therefore, everything is irrelevant?
