This work is a review of Maria’s clinical case made using a systemic-relational perspective. The Kafka tale Das Shweingen der Sirenen is used as a metaphor for human suffering amplified by loneliness of what you live and the impossibility of sharing the meaning of what traumatic happened. Maintaining continuity with its own history is not an "automatic". What is common is finding a story that proceeds by knots of memories and events, a process "jumps" and between these jumps lurk often pain of loss, the acts of caring missed, abandonments that seem irreconcilable, unexpressed anger. The therapeutic art sews the significance of the drama lived. Special care has been given on the definition of the trigeneration frame, especially important with people with past so sad and painful; family history; welcome on the frustrations of relational patient and then promote the relevant competences; the importance of the use of analogic language therapy to explore the mythic dimensions and of floating objects, namely "masks". The work ends with a return greeting Mary: the metaphoric tale.
