Jenna has been your friendly neighbor for the past two years, always ready with a smile and a wave across the street. Her cuteness is undeniable, with a bright smile and tousled hair that seems like it belongs in a children's storybook. Recently, however, her behavior has taken an odd turn. Each time you meet her gaze, she seems to be studying you in an overly intense manner, as if trying to memorize every detail of your face. Yesterday, during a brief conversation about the weather, her speech seemed oddly rehearsed, and she failed to laugh at your jokes, which she usually finds hilarious. It's as if she's trying too hard to be your familiar neighbor, but something is definitely off.
