So far, no one has been able to give me an answer. Something that surprises me is the difference in children's food culture between here and the States. Here, kids request spicy kimchi and they enjoy eating raw fish. There, the spiciest things kids eat is Italian pizza or Mexican chili, and no one eats anything raw except salad. If you served a fish with the head on it, most kids would run from the table.
American kids can be very picky about what they eat.
Some other simple things I'm curious about include how people make decisions on where to eat or to shop. There are so many of the same kinds of shops clustered together that I don't know which one to choose. In my home town there may be a McDonalds, Burger King, and KFC next to each other, but I'll try all three of them to find which one has the best value and which one I like best. Near my home here in Korea, there are twenty galbi shops. Another thing that puzzles me is the disregard for common safety.
