W: Can I help you?
M: Yes, I'm looking for a gift for a Japanese family here that I'm going to stay with. What do you recommend?
W: Pen sets are always a good gift.
M: Isn't that too small? You know... I'm here to learn Japanese in a college for a whole year. I think it's a long time and it'll be a great trouble to the family, so I'll...
W: Well, I see... But we Japanese consider it important to respect each other, rather than give expensive gifts.
M: Yes, all right, let's see pen sets. There's sets with a pen and a pencil, and bigger sets with four pens.
W: Don't give a set of four pens to your Japanese friend. In fact, don't give four of anything.
M: Why is that?
W: The Japanese word "four" sounds like the word for "death". It means bad luck.
M: Thanks a lot. In that case, I'll take the single pen and pencil set.
W: Good choice. These sets make very good gifts. After all, pens write in any language.
M: Right.
