These short stories tell the fragility of the niches, where many are hiding close ourselves off to the world and protect yourself from its events, assured of their inviolability. But the fiction does not last long, the world knocks at their door, annihilating the joints naive, calling them to account for their past, their beliefs, their life. So what to do? Reject the world to the bitter end, perhaps isolating and sacrificing themselves? There is no one correct answer or more right than the others. Indeed, perhaps someone realizes he locked inside a shelter without sense and discovers that the world is much better.
