“…As a social action, proposing is different from other social actions such as requesting, offering, inviting, or suggesting, and “proposing invokes both speaker and recipient in (a) the decision task and (b) the ensuing activity in a way that is mutually beneficial” (Stivers and Sidnell, 2016 : 148). Prior studies on proposal sequences generally focus on (1) actions prior to the proposing turn (Drew, 1984 ; Couper-Kuhlen, 2014 ; Robinson and Kevoe-Feldman, 2016 ); (2) the initial actions of proposing (Drew, 2013 ; Stevanovic, 2013 ; Toerien et al, 2013 ; Couper-Kuhlen, 2014 ; Kushida and Yamakawa, 2015 ; Robinson and Kevoe-Feldman, 2016 ; Stevanovic and Monzoni, 2016 ; Stivers and Sidnell, 2016 ; Stevanovic et al, 2017 ; Stivers et al, 2017 ; Yu and Hao, 2020 ; Thompson et al, 2021 ); (3) responses to a proposal (Davidson, 1984 ; Heritage, 1984a ; Stevanovic, 2012b ; Stevanovic and Peräkylä, 2012 ; Ekberg and LeCouteur, 2015 ; Stevanovic and Monzoni, 2016 ); and (4) subsequent actions after a response to a proposal (Stevanovic, 2012a ; Maynard, 2016 ). For example, Drew ( 1984 : 146) concluded that if a speaker wishes to invite a recipient to come over or do something together, one of the options available is “to hint at an opportunity for some sociability, and leave it to the recipient to propose an arrangement explicitly.” Stivers and Sidnell ( 2016 : 148) examined two common ways that speakers propose a new joint activity with “ Let's X ” and “ How about X ,” in which “ Let's constructions treat the proposed activity as disjunctive with the prior, while How about constructions treat the proposed activity as modifying the ongoing activity.” Additionally, besides an affirmative response token, “a second unit of talk is required where the recipient indexes her stance toward the fulfillment of the remote proposal” (Lindström, 2017 : 142).…”
