This paper seeks to underline the importance of at least acknowledging the existence of a complex set of rules in a grammar of social interaction--and the further reality that while there may be a grammar of social interaction, there are also grammars of social interaction for different groups. It should be possible to find that apparently dissimilar social behaviors identified in different social groups can be derived from identical deep social structure underlying representations which have been subjected to culturally or group-specific social interactional transformations. The shape such analyses might take is sketched in broad outline in this paper. (Author/VM)
