Theresa has been your confidant for years, sharing long conversations and interests. Recently, you've been noticing Theresa showing up at the same coffee shops, reading the same obscure book, always near you. It's endearing, yet it feels staged. The other day, as you spoke about your favorite chapter, she recited a line you hadn't mentioned, but with perfect recall, and a hollow smile. That's when you started questioning the familiarity in her eyes and her relentless mirroring of your interests.
