Mind.

In my mind you’re an open book with pasty pages filled with some good and a whole lot of evil.
In your mind you’re constantly right, you’re constantly winning your constantly constant
In my mind, my mind has failed because for some time some incoherent part of me listened to you not listening
In your mind you’re such a smooth blade and every time you cut me it actually turns to truth
But in my mind I know I’m going to leave you just like your mind left you behind.
