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.
