Why?

I can't even be around you anymore.
Over a three-day period,
I've changed my mind about you.
The most hurtfully words in the dictionary,
Can't explain how much I despise you.

I'm going to make you regret even looking at me.
I'm going to make sure your life is a living hell.
I'm going to make you crawl under a rock and die.
Lies, lies, lies.
Four simple letters,
Put together such meaning.

We were never close.
The way you looked at me,
Is what brought us closer.
I was too blind and stupid to see what that look actually meant,
Lust.

Four simple letters,
Put together such meaning.
And over all,
I like that I can take my anger out on you.
There is no one else I'd like to do it to more.

I'm going to make you want to kill yourself.
I promise that.
God help you,
Cause you're going to need it.
