"Just a simple wrench, who decided to move on from it's dirty and oily life. This wrench ran away from a chop shop, went through many and many difficult courses to get here. It even fought against crowbar, but apparently poor wrench had no choice but to run away. Until one day a screwdriver found poor wrench lying down near a trash can, with nowhere to go, wrench just stood and waited till someone picks her. Screwdriver saw wrench and asked poor ting to follow it, so wrench did. Screwdriver calls few bolts and screws and those bring a sheet of paper with some notice, advertisement, so they carefully read. "Wrench, you go here, and get yourself a life. I have my bolts and screws here and I cannot simply leave this place alone." Wrench left, bowed to the Screwdriver and thanked for help given. Wrench departed to unseen adventure. What kind of adventure it will keep on having, is for you to decide."
As for what happened to poor Wrench, or more full and/or detailed story, comment down. or just ask for it.
I just typed it down real fast. so its a bit random.
