the table manners. In China, people use chopsticks to eat and they
are supposed to eat without making a noise. But in Japan, it’s polite
to make a noise when you are eating noodles or drinking tea,
because that means the food is delicious and you thank the meal
maker. In western countries, people use knife and fork at table. But
American table manners are simpler than those in Europe. Western
people may use more than one set of knife and fork at dinner.
