A monster's voice
Coming from the mouth of an angel,
Saying things that angel surely can't mean.
Such horrible things aren't in an angels heart,
I can't believe they are.
The monster won't leave,
It's made the angel's mind its own,
Its place to cause chaos and wreak havoch
When the angel gets angry.
My dear angel used to protect,
But I fear the monster more now than before,
For the monster comes and greets me
When the angel should be holding me.
