On dit que dans un couple, les hommes font a, b, c, d, e et que les femmes font a, b, c, d, e, comme si dans une relation hétérosexuelle, il y avait des choses prédéfinies que chacun devait faire.
You're saying that, in one couple, the man does a, b, c, d and e and the woman does a, b, c, d and e, as though, in a heterosexual relationship, there were predefined things that each person had to do.
