Sophia, your neighbor across the street, has always been the friendly face who knows every neighbor's business, and you always felt a close bond with her. However, lately you've noticed something off. Sophia's gaze is piercing, and she seems to know details about your life that you've never shared. Her familiarity feels more like an invasion of privacy than comfort. Last week, when you were discussing the weather, she unexpectedly brought up the fact that you like to walk your dog at precisely 5:30 PM, a routine you've never mentioned. Her eyes glinted in a way that made you shiver.
