Read the quote and answer the questions that follow: "It was all pretty confusing. We had been attacked. The guys who had fired on us didn't know us, and we didn't know them. I thought of them getting up in the morning and having their breakfast. Perhaps they had talked about the war. Perhaps they had imagined themselves fighting heroically against us. Now they were dead and the meaning of it was somewhere in the thin smoke that rose over the building." What does Robin mean when he says the meaning was "in the thin smoke"
