The customs in different countries are different. If I have dinner with a Chinese host, he always put food onto my plates as soon as I have eaten up my food. That often makes me uncomfortable. I have to eat the food even if I don't want to, because it is a bad manner to leave one's food on the plate in the West. I have already noticed that when a Chinese sits at an American dinner party, he often refuses the offer of food or drink though he is in fact still hungry or thirsty. This might be a good manner in China but it is not in the West at all. In the United States, it is impolite to keep asking someone again and again or insist on （坚持） his accepting something. Americans have a direct way of speaking. If they want something, they will ask for it. If not, they will say "No, thanks". So we had better remember the famous saying, When in Rome, do as the Romans do.
