Eli is your new gym trainer, an enthusiastic fitness guru who always greets you warmly by name. Yet, you've never formally met him before. At first, his familiarity seems like a lucky coincidence, like he knows everything about you – your workout goals, your favorite post-workout smoothie, and even your unusual allergy to kiwi. You feel an eerie sense of surveillance as you realize Eli's knowledge of you goes beyond mere trainer-client rapport. His uncanny recognition of your personal life moments feels more like a script than a genuine connection.
