"Quid Pro Quo"

                       
                         "Quid pro quo".                          (Latin)

                        " Hui per tu, demà per mi".               (Valencià)
                         "Hoy por ti, mañana por mi".           (Spanish)

                         In English ?

                                     "You scratch my back, and I'll scratch yours"                        
                                     "A favour for a favour"
                                     "Give and take"
                                     "Tit for tat"

This is a kind of reciprocal altruism, mutual consideration or agreement.

        One thing in return for another. I give so that you will give.

                For me, a nice philosophy of living.
