The main purpose of this paper is to approach some issues concerning intersubjectivity in fieldwork. The field experience addressed here was conducted on the Portuguese-Spanish border area demanding from the author to move across the border and assume, on a daily basis, her status as a Portuguese citizen like half of her interviewees as well as being a foreigner like the other half. One situation that was particularly relevant regarding the level of researcher’s identity was caused by the dual-perception subjects formed about the anthropologist: being Portuguese like "us" (anthropology at home) or being Portuguese like "them" (anthropology abroad). Within this framework of reflection this paper looks at the interactional process through which knowledge is acquired, shared and transmitted. It also explores the dynamics of the subject-researcher relationship in order to understand how this relationship influenced both collation and analysis of the author’s data.
