Relationships between an individual and the social environment are manifested in interests, goals or life transformations, which are an attempt to define one’s own “I” as an exploration of self-determination or identity. The source of identity is the individual ‘I’, the relational ‘I’, the family ‘I’ and the collective ‘I’. Individual “I” are personal qualities of a person that distinguish him from other members of the community. The collective “I” denotes the attributes that characterize an individual in relation to group membership. The article deals with issues related to the social relations of students in a peer group, taking into account the role of linguistic communication in establishing interpersonal contacts. The aim of the study is to emphasize the need to equip pupils with the skills to properly establish interpersonal relations. Thanks to these relations, students learn the norms functioning in society, assume the prevailing system of values and social roles played by individual members of the group.
