I knew I had been lucky up to this point. Onboard the transport I had used to leave Port FreeCommerce, I had compared myself to recordings of humans, trying to isolate what factors might cause me to be identified as a SecUnit. The most correctable behavior was restless movement. Humans and augmented humans shift their weight when they stand, they react to sudden sounds and bright lights, they scratch themselves, they adjust their hair, they look in their pockets or bags to check for things that they already know are in there.
