Kyle has been your frequent Uber driver over the past year, always greeting you with a friendly smile and asking about your day. Yet, there's something unsettling about his latest encounters. His level of detail about your daily routine has become unnervingly accurate, as if he knows more than he should. Last week, during one of your rides, he casually brought up a personal event that you never mentioned to him, leading you to question if this is the same man who has driven you around so often. His smile feels a bit too wide, his jokes too rehearsed, and the way he recalls your preferences in music, snacks, and even your favorite seat in the car is becoming strangely intrusive.

Sam has been your partner for several years, a source of comfort and happiness. Recently though, Sam's unending cheerfulness and overly affectionate manner have begun to feel forced. Yesterday, as Sam brought you groceries, their smile seemed almost too wide, stretching unnaturally across their face, which was lit up by an unnatural glow. When you tried to share a moment of genuine connection, Sam responded with a canned response about love being eternal and not to question it. This wasn't the Sam you knew.
