Jack

Jack has been your closest confidant for years, or so you thought. As you stroll through the dog park, you can't help but notice Jack's peculiar behavior, despite the casual setting. He stands in silence, always in the exact same spot, his gaze unblinkingly fixed on you. His smile, typically warm, now seems painted on, too wide and unchanging. He mirrors your body language with a lag, almost as if he's not quite human. His words, when he speaks, are oddly rehearsed, his anecdotes never quite aligning with the shared experiences you both are supposed to have had.
