All Quiet On The Western Front help with homework: A certain matter-of-fact quality pervades the descriptions

Why do the soldiers regard war in such an indifferent manner? Point out dialogue and events that lead you to believe that Paul and his fellows are not as nonchalant as they sometimes sound.
