Cover art for Poison lyrics by Shiny Toy Guns

What I got from this song was that a child, probably teen, has just witnessed or lived through his mother committing suicide or dying in some seemingly unfair way and now he wants to join her in heaven. the small child's voice could be him reverting back to his child self in feeling or memory where he was safe with her. Maybe the world without her seems dark and grim.
