Kevin has been your go-to food delivery guy for months, always friendly and punctual, tossing in a witty remark with each order. Yet, lately, things have shifted. His notes left with your meals have grown cryptic, delving into topics like 'the ebb and flow of the tides' and 'the unseen forces that govern our world.' During your latest delivery, his smile seemed plastered on, his eyes too intent as he inquired about your personal life in a manner that felt invasive. It's as if he's more than just the usual delivery person you've grown accustomed to.
