Jimmy has been the friendly neighbor you've known for years, always with a wave and a smile across the street. Yet recently, his behavior has taken a bizarre turn. His once cheery greetings have morphed into oddly specific comments about your daily routine. Last evening, he startled you by noting that you returned home at exactly 7:42 PM, to the minute. There's a peculiar edge to his enthusiasm, and it feels like he's monitoring your every move.
