Aliens

Aliens came surreptitiously and possessed human bodies so only our minds were different. The aliens cleverly kept body functions, gestures, and speech patterns the same. You could tell that a person was inhabited only if you were inhabited, but you wouldn’t tell. Nevertheless, they took over. If you suspected this, you’d wonder whether everyone getting into positions of power was an alien. You’d wonder whether they formed couples with humans, or only cohabitated with each other. You’d wonder whether they had a master plan, like ants, or whether everything was transactional as for humans. Did they begin to have feelings, like teenagers growing up? Did they experience sorrow or joy, or boredom, or were they just faking it? Was it a difference that made a difference?
