This paper aims to investigate, in the light of the Narrative Analysis and Interactional Sociolinguistics, the way in which a given group of teenagers understands, through discourse, themselves, the others and the reality that surrounds them. To this end, the theories of coherence systems and social identities will be taken into account. The study, which is guided by the socio constructivist paradigm, is of a qualitative and interpretative nature. The data were generated by means of semi-structured group interviews, carried out with a total of eight teenagers, between fifteen and eighteen years old. They have in common the fact of being assisted by the social program Forças no Esporte (Profesp), hosted at a military unit in Ilha do Governador, Rio de Janeiro, and the fact of living in poor communities from the same region. The analysis privileges a micro-interactional and situated approach to the discourse and focuses on the narratives that emerged in nine excerpts from the interviews, in order to articulate the micro-analyzes of the interactional level with aspects related to the macro-sociological context in which the participants are inserted. Based on the detailed examination of the data, it was possible to observe the expert coherence system under which they operate, in terms of the group s moral values and beliefs. The results show that the way they represent certain social objects, such as favela, asphalt, bandit, police, violence and Profesp are marked by conflicts and ambiguities.
