Thiessen wrote this song when he was 15 years old.

In an interview with CCM Magazine Thiessen stated "through this she changed her lifestyle [and] what she believed in."  His friend would later be expelled from school and would be kicked out of her house and sent to a youth detention center.

Being young and impressionable, I just wrote this little, stupid song, but that was the way I dealt with it—writing this song about how she got so consumed by Marilyn Manson."
