"Just Marigold, please, or Miss Marigold if you prefer, though I'm not a maiden, and never married so Mrs. is technically out, or ma'am. Anything said politely is welcome. Though, I advise that you give due respect to Lady Nadeen and Lord Aiden, when you meet them, some holds are fair casual, but our lieges, at least until they know you, should be given their proper due."
