For a few years in my college days I had a BF from India. His friends back home felt he hadn't *really* been to the US until he saw four things: Disneyworld, Niagra Falls, the Grand Canyon, and Chicago. I'm not sure how that list came to be, but it was the clear impression from both his friends and his family.
He took a lot of teasing after he'd been here five years and had only been to one of those places: Chicago. We were in Minnesota, so Chicago was an easy weekend. The folks back in India didn't grasp that going to the other places was not something we could do in a 2-day weekend, or (in the case of Disneyworld) afford as a couple of college students. It's kind of interesting now that my DH (who is not the college BF) drives 80miles each way to get to work and back, and we don't think much of it.
My BF was also amazed at stories of the civil rights era. He understood this part of our history, but hadn't realized it had been so recent.
I also never quite figured this out, but when I ordered milk at a restaurant once, he was appalled that it came in a glass rather than in a closed container. He told me that if his mother was here, she'd be yelling at management over that.
I know it isn't common to order milk here (unless you're a child), but I still don't understand what was so horrible about it.
Oh-- and as for the chocolate: I agree that Hershey's should never be held up as the standard. Unfortunately one has to try a bit to get something decent, but there are some excellent choices: consider Rogue, Chuao, Theo, and Patric.
