In this work the authors present their vision of the alliance and intimacy of couples on a journey that started from a distance, from the myths of the greek world through oriental philosophies and rituals of some primitive and archaic forms of European folklore to finally land the dance of sexual differentiation: the tango. The authors highlighted the intimacy in couples is characterized by a perennial condition of solitude without which it would have no way to exist on the very concept of couple. The human condition of sexual limit leads man and woman to a continuous research to move beyond the solitude. The "we" is therefore this in couple. The journey begins from Hermaphrodite looking for his half, her half an apple, not to be "alone" and ends with the two tango dancers. They dance in pairs loneliness. As a couple you can be "alone" but you should not feel "alone".
