Out of reserve, I was not able to say "Yes, I will," because (1)that would require her to prepare breakfast for me 5 alone. I had no choice but to say, "No, thank you.

When I was back at the university after the holidays, I (3)brought up the subject with a few Americans. 4)"If you had been in my place, and had needed breakfast, what would you have said?" One person said, "Your friend's mother was being frank, so I'd 00.00% 10 have said frankly, 'If you could prepare a little breakfast, I'm sure I'd enjoy it. (5) Otherwise, I'll eat out." Another person said, "That's not so polite. I'd have asked her politely, 'If you could prepare breakfast for me, I'd appreciate it." They asked me why I had been reluctant to give a frank opinion. I explained the Japanese cultural viewpoint. In Japan, immediately accepting an 15 offer of a meal is regarded as impudent; such an invitation is supposed to be declined at least once. But the host realizes that the guest has declined out of reserve, and makes it a rule to ask a second time. A Japanese guest never insists on being served a meal. The host understands the situation and the feelings of the guest and reacts appropriately. (7) "That idea has no chance at all of working here," one American said with total frankness. She continued, "Unless you're frank here, you'll go hungry all the time."
