Hello, Stranger, waiting in my chest
There has been war between us in the past
But I end this war at once, I end this war at last

Hello, guest, who lays in my lungs
I once thought you and I were one
A misinterpretation which causes a many to reach for a gun
So ignore you I did

Hello, Friend, who sits heavy in my heart
What shall I learn today?
What beasts will you encourage me to slay?

Command me sister, use the wind
Direct me brother, use the stars

Finally old friend, I am ready to start.
