PurposeThis article seeks to provide a fresh perspective on the methodological approach to studying caregiving in a transnational context by analysing, local caregiver’s lifeworld, informal interpreting/translation and professional communication with foreign retirees.Design/methodology/approachThis project explores the complex and multifaceted meanings of everyday objects through diffractive vignettes to illuminate the communicative entanglements that arise between caregivers and foreign retirees receiving care in Thailand. To identify intra-actions in caregiving, we collected data through informal interviews, observations and various artefacts before combining them in a group of potential communicative relationships by creating a narrative summary of situations.FindingsCommunicative relationships in the vignettes are multidimensional, with diverse logics underlying choices, rapport formation and communication effectiveness. This premise also illuminates how caregivers perceive and intra-act with their accommodation strategies, considering trust, comfort and comprehension. Our findings were also discussed with the concept of communication accommodation theory.Originality/valueAs an extension of the post-humanist approach to the diffractive reading of vignettes, this study sees its value in studying agent-related informal translation/interpreting and human-to-human relationships.
