Social Education implies a constant exposition to human experiences of vulnerability and suffering. In this paper, Levinas's philosophy of alterity and, specifically, the notion of hospitality constitutes our ethical lens to explore educational encounters in non-formal contexts within the Spanish Social Sector. The study is developed from a hermeneutic phenomenological approach into the depth of lived experiences of eight social educators who currently work with different populations groups. The testimonies, explored through semi-structured interviews, are presented in a conversational, dialogic, poetic format. First, Levinas' philosophy is presented as our ethical position, focusing on subjectivity as hospitality. Secondly, methodological aspects regarding hermeneutics are addressed. Finally, the testimonies of social educators are presented in an evocative way, exploring uncertainty and three different tensions regarding human relations in their practices: physical spaces, affection, and embodiment.
