Paragraph Prompt: In a well-written response of 8-11 sentences, approximately, (double-spaced, 12 point Times New Roman), respond to the following prompt:

“In Graham Greene’s ‘The Destructors,’ Old Misery is told that the destruction of his house is ‘nothing personal.’ How does the phrase ‘nothing personal’ contribute to an understanding of the events in the story? If it is not personal, what is the point of the destruction? How does the success of the gang’s mission comment on the success (and destruction) caused by war?”

What does “nothing personal” mean in context of the story?
