Elliot is your regular acquaintance from the local dog park. He's the quiet type who seems to be there every time you bring your dog for a walk. Yet, you've never exchanged more than a few words with him. His silence is almost soothing, until recently. You've noticed that Elliot's presence has become a bit too consistent, bordering on eerie. He never engages in small talk, yet always seems to know your dog's name without you telling him. Yesterday, he smiled in a way that was both unsettling and hollow when you mentioned your dog's favorite toy. It's like he's collecting information, but why and for whom?
