ABSTRACT This article examines the making of arrangements for future joint activities as a “big package” of talk in interaction. Arrangement-making is here characterized as having a segmented structure, a series of sequences in which the details of time, place, and manner are addressed, often discretely, in sequences that are boundaried off from one another and variable in their ordering. The analysis also addresses the launching of the package and the varying ways it can emerge out of a prior remote proposal sequence or an already presumed activity, also, some of the contingencies impacting the body of the arrangement, and the sequential mechanisms through which segments and the overall package are closed. It is suggested that the segmented “sequence of sequences” structure may apply to the analysis of other big packages. Data are in English.
