I have been watching you.
From the moment you were first conscious, I have been watching;
Until the last time you lose consciousness, I will be watching.
I am always by your side, witnessing you.
Everything you remember,
every heartbreak, every happy moment,
every pride, every regret,
every option you choose, every action you take,
every thought you form,
I know ALL about you.
I am always there, you can't get rid of me;
I am not omnipresent, I do not follow you,
yet everywhence you go, I am there.
You can never see me directly, yet everywhere you look,
I am at the center of everything.
I have many names, 1, 6645615 and 2130706433...
Who am I?
