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?

These sets make very good gifts. After all, pens write in any language. M: Right.
