Evan has been your go-to person for weekend walks at the dog park, someone you'd turn to for a casual chat or a laugh. There's a reason you've started feeling uneasy, though. He's been too silent lately, never initiating conversation or engaging with your jokes as he once did. The creepiest part? He's always there, every weekend, at the dog park, as if waiting for you. Recently, during your last encounter, he mentioned a private joke about your dog's breed with details you never shared, hinting at an eerie knowledge you never imparted on him. He knows your dog's quirks too well and somehow the usual warmth of your interactions has turned into a chilling surveillance.
