The setting: a 747 just reaching cruising altitude.
Personae: me and the Mystery Woman and a flight attendant.
Flight attendant: “Would you like something to drink? Coffee, tea, pop?"
Me: “Why do you people up north call soft drinks ‘pop’ instead of a real name?
Mystery Woman: “Why do you boys from Texas call pop “Coke?” -- and she means all kinds of pop are called Coke.
Me: “That’s urban myth. We don’t call all drinks ‘Coke.’”
MW: “Do too.”
Me: “Nuh uh” as I crossed my arms and assumed the sulking position.
MW, after stewing only a minute: “The pilot just announced we’ve reached 30,000 feet. Did your ears Coke?”
