Unaccompanied child and youth migrants negotiate with local host communities in their attempts to find a place to belong to, yet research has generally neglected their participation in the making of relationships with the people around them. Providing a perspective of the longue durée, the Zimbabwean–South African borderland teaches us that time is critical in young migrants’ ability to negotiate their positioning and actively shape relationships with host communities, based on mutual interest. While at the beginning of their stay, unaccompanied children and youth were at the mercy of others, time enabled them to accumulate knowledge and develop skills that were in demand, shifting their place in society and setting the ground for conviviality.
