Abstract
In today's societies relationships between near relatives and friends appear to be somewhat paradoxical. Some accounts present them as the social ideal, exalting the solidarity and altruism represented by proximal relationships. By contrast, others point to the social dangers in such relationships when they are conducted in the public sphere. In order to grasp the coexistence of these opposite views, this article attempts to place proximal relationships in the explanatory context of a gift economy, a concept with a long history in anthropology and which has lately been the focus of interest of a significant group of social thinkers.
