This is how I want my life to end
Hooked up to a prison sentence
With the phone lines down
And machines treading water for me

This is what I want
When death has already taken my spirit
When death has already taken my song
Promise me you’ll keep the heat on
In the empty house

Please force me to keep living
In such a condition.
I know your cruelty is a sign of love
