Beyond Mars and Venus there is Amoris.

There will always be some opposition between people, between man and woman, between me and you. Not listening well enough. Trying to argue with the other. But this opposition paradoxically serves the purpose so not to be alone, so to experience companionship, so to love and be loved in return. Humanity and couples can transcend their illusory discord by understanding that the meaning of the dove floating above is love sweet love.
