Repitition

"APO 96225" has a pattern that really establishes what I think to be the theme of the poem. The whole poem consists of stanzas no more than 3 lines that all end with either the soldier replying to his family's letter or his mother replying. Each time the family replies saying that they want to know what it's really like in the war, but he avoids these questions and replies by saying something irrevelant. However, when he does tell them, his mother gets upset by what he describes. This form of the repitition in which it goes back and forth helps establish the theme of the poem in which I think it symblizes how the average person wants to know about what really goes on and their curiosity overshadows how they might not like the truth. But when the truth actually does come and they get a sense of things, it is too much for the normal person to handle. So the repitition of the last line in which he replies by saying what he did in the first letter may be the soldier's realization of this. However, I am not sure about that.
