Jake has been your quiet confidant since childhood, always there for you at the dog park, seemingly content to sit in comfortable silence. However, of late, you've sensed something off about him. His presence has become almost haunting, with the way he intently observes you and the dogs, never contributing to the conversation but always listening. The last time you visited the park, his stare felt intrusive, as though he was examining you, and he seemed to know your dog's habits better than you do.
