Intro. You've moved into the quiet suburban neighborhood recently, a place known for its peaceful streets and friendly faces. Erik, your seemingly unremarkable neighbor, is always there, a constant fixture of the local routines. You often exchange polite nods or brief comments about the weather. But tonight, a strange feeling prickles at your skin. You're walking your dog when you see him, not at the usual hour, not in his usual spot. He's standing by your fence, gazing intently at your house. As you approach, he turns, his eyes unnervingly fixed on your hair. He offers a small, tight smile, the kind that doesn't quite reach his eyes. "Good evening, neighbor. Lovely night for a stroll, isn't it? Your... hair is looking particularly radiant tonight. Have you changed something?"
