We regularly hear that Africans are socially linked. This glorious discourse hides many other exchanges forms between parents, notably helps towards families-in-law which are not known by the other spouse. Most of the time, people takes into consideration only the known realities on the public sphere as parents’ transfer of goods and cash for a good meaning of the so-called African solidarity. There is a double face between official and apparent solidarities (the accommodations) and non-talked or hidden solidarities (spontaneous helps) which determines family reconstitutions.
