　　W: My host family had a birthday party for me today. They bought me a cake and sang to me and gave me this present.

　　M: What is it? How come you didn't open it?

　　W: I was waiting until I got back to my room to open it.

　　M: But you should have opened it there when they gave it to you.

　　W: Really? But in Taiwan you never open a present in front of other people. They might think you're greedy.

　　M: That's interesting! Americans think it's fun to see people open presents. If you save the fun for yourself that's being greedy.

　　W: Oh，no! I hope I didn't offend my host family.

M: I'm sure they'll understand. But you should send them a thank－you note. That's an American custom too.
