Social Science assumes, as our human experience daily confirms, that social life is orderly. This paper proposes to document the detailed orderliness of actual conversational interaction, show that participants orient to this orderliness, and explicate the knowledge--together with the rules for situated use of this knowledge--which members actively use in accomplishing this orderliness. The data are public and consist of tape recorded natural conversations in the Lue dialect of Thai, transcriptions of those recordings, and word-for-word glosses and translations of the transcriptions.
