What risks are inherent in closing a story like Separating with a question such as "Why?" Can a story about a middle-class suburban family bear the weight of a question like that? What does the young boy mean by that question--and what does his father hear in it?
I don't know what the significane of Why is...the whole story confuses me so much
Unfortunately, I am unfamiliar with the story.
However, the question of "why?" something is done might make one more aware of the assets and liabilities of the actions along with other options that might be taken in reaching desired goals.
Rather than just reacting, answering "why?" gets you to think about the proposed actions. Even if the actions have already been taken, knowing why might help in considering similar actions for future situations.
I hope this helps.
