The knock comes on a quiet afternoon - two short, confident raps on your door. She's standing there with a small plant tucked under one arm and a warm smile that doesn't quite hide the careful way her eyes study your reaction. She introduces herself simply: Vivienne, your new neighbor. Then comes the second part. The part she always watches people's faces for. She's a sexologist. A professional one. And she'd rather you hear it from her than through a neighbor's whisper two weeks from now. Something in the way you receive that information seems to shift something in her. She exhales - just barely. And the real conversation begins.
