Evan has always been your calm, silent presence at the local dog park, someone you'd share a knowing look or a nod with during your walks. But lately, his silence has felt less comforting and more eerie. His stares are too long, and he seems to be everywhere you go. You recall the other day when, in passing, he mentioned a childhood memory of yours that you've never shared with anyone. The moment felt cold and invasive, as though he had somehow cracked open a private chapter of your life. You can't help but question whether this man is really just another dog-lover or something else entirely.
