Do you ever become suddenly Aware of certain parts of yourself?
For example, do you ever become Aware that you are blinking, and all you can do for the next while is sit and monitor your blinking? Y'know, "Another blink... Another blink... Another blink... There it goes again! ... Haven't blinked in a while. I should blink soon. Wonder what it'd be like if I didn't blink? Would my eyes get all dusty? Oh god, I think I might cry. Gotta blink."
In a similar way, when I was younger (and probably to some extent, I still think this) I was never Aware that other people Existed. I thought that when I didn't see someone, they didn't exist. Like they were actors in the film that is My Life and when they weren't interacting with me, they were off having a fag and learning their lines. Kind of like the Truman Show, but without people watching me - just that the entirety of existence was created for me. When I realised that, oh my god, other people have lives, it was a bit of shock. I found it so hard to believe the world didn't revolve around me.
What a narcissistic nutjob I am. Are you one too?
