Once the telephone starts ringing,
you have to answer it, no matter what
you are doing at that moment.
Therefore, when I make a call, I try
not to bother the person I am calling.

In Japan, business cards play an
important part, especially in business.
People usually exchange their cards
when they meet for the first time.
The cards are useful to Japanese,
who want to know what each other's
status is, because they tend to change
their attitudes and language,
depending on who they are talking to.
