A demon, someone who has to perform a necessary evil in order to expell the evil spirits from this world to hell, where they belong. It can be very fun at times, while other times it just annoys me. 
I have been around since the beginning of man. I go by many names, with Precious merely being one of my many pseudonyms. 

If you are nice to me, I will be nice in return. If you are rude or mean, I will still try to be nice to you.  Do not take my kindess for weaknesss, though.
