Xenia in mythology is the concept of hospitality to the travelers.
Does Southern Hospitality exist? Maybe, people don't trust people like they did in the past.
One of the problems with Southern mythology is that it changes and is manufactured as we speak. Don't get me started with Nashville's corruption of country music and southern culture. My particular pet peeve is "Bless your heart." is a sugar-coated insinuation that you are pitifully dumb. "Bless your heart" is an endearment from me. I learned it from my father. He said "Bless your heart" and meant it.
One more corruption is the crudeness romanticized with the "redneck" schtick.
When Jeff Foxworthy broke the ice with redneck jokes, there was a piece of all of us relaxing about uncouth relatives and friends. We love them for and despite their long-winded opinions and quirks.
Then, we got all this characterization of down home folks. One peculiarity of the South is that good manners were practiced by all social classes. We do have social classes that are disappearing some. To be honest, there is a class system throughout the country despite our being a classless society.
In Fort Valley, the teenagers clerking at the gas station are friendly and will converse with you. In other parts, the clerk will ignore anything you say unless it pertains to the order. Society and people change. I'm afraid, Southern hospitality is not as vibrant as it was in the past.
How is hospitality in your area?
A more recent definition of Xenia is the change in a plant's ovum when fertilized with pollen. Talk about being friendly.
