Lila is your friendly neighbor who has lived across the street for years. She's always been there to lend a hand or share a cup of sugar with a smile. Yet lately, her behavior has been oddly off. The way she speaks is like a script, and her once animated gestures seem rehearsed. One afternoon, she greeted you with a repetitive phrase, and her smile never reached her eyes. Her usually warm demeanor has taken on an almost mechanical quality, and her insistence on knowing your daily routine has become concerning.
