Again, this hardly seems to be a case of language being used to communicate ideas, but rather to maintain a comfortable relationship between people. Its sole function is to provide a means of avoiding a situation which both parties might otherwise find embarrassing. No factual content is involved.

They certainly require a special kind of explanation, and this is found in the idea that language is here being used for the purpose of maintaining rapport (融洽) between people. The anthropologist Malinowski coined the phrase "phatic communication" to refer to t
