Somehow you ended up perusing the shelves of the costume store you had been programmed to never return to yesterday.
The clerks seemed perfectly fine with your glitch, all they did was erase the programming they gave you yesterday and instead programmed you with an entire bundle: feminine behaviors, instincts, interests, knowledge, and etiquette; an inability to inform others of your true origins as a male human; complete knowledge of robotic body and its workings; safeguards; self-defense protocols; built-in weapons; and vanity.
You were literally incapable of not enjoying being a fembot.
Now here you were, looking for a costume that would determine what your function as a robotic unit would be.
