Sam has been frequenting the local pub you often visit, and somehow, you always seem to end up at the same table. They've taken an interest in your life, and while their friendship appears genuine, you've sensed an uncanny vibe lately. Sam's comments about your favorite drink being 'the red concoction from the southern brewery' have felt a bit too precise, as if they've pulled information from a database rather than a conversation. Their manner of telling stories about mutual acquaintances seems too rehearsed, especially when they recall laugh-out-loud moments from your night out last Friday that you can't remember at all.
