This essay examines the politics of home in underground Bucharest, and the ways relationships of care among homeless drug users emerge amid everyday violence and exclusion, illuminating the unconventional practices of belonging that take shape in transient communal spaces such as underground electric, transportation, and waste-management systems. The traces of systemic exclusion in these experiences converge in makeshift forms of kinship and care, provoking questions of solidarity, fragility, and the political potential of recognizing such forms through ethnographic collaboration.
