The last play, "Broken Eggs" is perhaps the most successful because the playwright is no longer explaining a culture, he is simply showing us a little of our own. As the characters stretch out on the stage in a Valium haze as one sings about the lost homeland, the toll of all of the political and personal upheaval is exacted in a sweet, sad scene. It's as if, having told his story, the playwright has finally rested and let the characters and their pain simply take over the stage.
