A demon is mean
An Angel is nice

A demon accepts all
An Angel only accepts its own

A demon sees past the rules
An Angel only sees before them

A demon cannot be understood
An Angel has no secrets

A demon can be trusted
An Angel cannot

Why can Angels be trusted?
Because no one is perfect
No one can be fully understood
No one that is "normal" exists

Demons are the human race
The ones that are all around us

Angels don't exist, sorry
Nothing so perfect has ever walked on this earth.
