I Am

I am that person you can scream at
for thinking,
the one you hate,
the one you're showing.
I am that person you can fight with,
the one over money,
the one to create.
I am the one you should be nice to,
instead of decieve.
All you are is seeing,
but all you aren't is believing.
What you should know is,
I am your worst enemy,
I am the other half of you.
