"Bless their hearts!", "smack dab" are phrases I grew up with living in the Southwest U.S. If you didn't live in Texas, you did a fine job of researching the geography and the dialect of Texas. Well written.
All my life I have wanted to write, but I put my writing on the back-burner while I focused on making a living and raising a family. Recently, I have returned to creating fiction. I write F&SF, fan fiction and now --here -- more risque stories.
