I will never be a "Belle", too much Kansan in me. Yet, after 20+ years of living here, it can "rub" off. The thing that my old friends in Kansas notice is "flair". How one dresses, turns a phrase or as DZRose mentioned-the ability to tell someone off (velvet glove).
My daughter is NOT a Belle, but anyone north of Texas thinks she is! That girl has such a lilt in her voice and she flirts with her eyes to the point that those northern boys just melt.
