Brent, back when I was still living in Alabama, my parents bought a cabin at Lake Martin, Alabama. They had a BASS boat and they had it for almost a year before they invited my brother or I up there. It was my brother's birthday, and almost the 4th Of July to boot. They also invited a mother and her daughter that they knew from France. France is not quite as foreign custom wise as Afghanistan, but almost.
They were a family that was fairly well off, and only the daughter spoke English. The mom only spoke French, so the daughter had to translate. We proceeded to be loud and proud fun loving Americans for the 4th of July, at the lake. Mom and dad had fried chicken, and hamburgers and hot dogs and everyone was barefoot, and relaxed and just like you can imagine a family at the lake in the USA.
The French lady came outside and her daughter sounded astonished, as she looked at her mom. She had to translate and see said it was the first time she had ever seen her mom's feet! It was her first time to go barefoot! Then when it was time to eat, we all picked up the burgers, hotdogs, or chicken and ate with our fingers. Her mother had never in her life touched her food and eaten with her fingers. She always used forks or spoons or some utensil.
She likely went back to France and talked about what pigs Americans are. The men sit around shirtless, wearing just a bathing suit, and eating a piece of chicken with their fingers and drinking a coke right from the can was just common, and something she had never seen before.
