...of culture

Connor described his golf game. There had been long silences all morning. Everyone in the foursome was polite and considerate, but spoken comments were rare and reserved. Most of the time, the men walked over the course in complete silence.
'And you had gone there for information?' I said. 'How could you stand it?'
'Oh, I was getting information.' But as he explained it, it was all unspoken. Basically, the Japanese have an understanding based on centuries of shared culture, and they are able to communicate feelings without words. It's the closeness that exists in America between a parent and child - a child often understands everything, just from a parent's glance. But Americans don't rely on unspoken communication as a general rule, and the Japanese do. It is as if all Japanese are members of the same family, and they can communicate without words. To a Japanese, silences have meaning.
'It's nothing mystical or wonderful,' Connor said. 'For the most part it is because the Japanese are so hemmed in by rules and conventions, they end up unable to say anything at all. For politeness, to save face, the other person is obliged to read the situation, the context, and the subtle signs of body posture and unstated feeling. Because the first person feels he can't actually put anything into words. Any speaking at all would be indelicate. So the point must be gotten across in other ways.'
