[quote name='craven_fiend']I am not a robot, I don't need sleep.[/QUOTE]
Well, someone you know may be a Robot; they could be friend, family, co-worker. It's good that you don't need sleep, because neither do they, and they can attack at anytime.
And when they grab you with those metal claws, you can't break free; because they're made of metal, and Robots are strong.
