THE OTHER SIDE by Ariel Dorfman
Atom and Levana: 30 years of marriage, they live in a small country house under the bombs of a war between two neighboring countries. The war finally ends, but the new border passes through their home and to go from the kitchen to the bathroom you have to show your passport to the Kafkaesque guard who monitors the couple's life day and night. Even the bed is divided in two and to find a moment of intimacy the two protagonists have to hide under it, in the few moments when the guard is distracted. And then this guard has a familiar look that resembles a sense of guilt: isn't it the son that years earlier the two parents had kicked out?
