Voices from near and far

I interpreted this story as being about a mother of several young men who are soldiers. The mother always listens to a radio to hear the names of the soldiers and she is always feeling worried about her sons. She is telling a message carrier what to write to her sons. She says to write that she is worried and that she wants her sons to write back to her as soon as she gets her message. The note taker never rereads what it is that he has written and that makes me suspicious that he was not actually writing what the woman asked him to. In the end the mother may have become suspicious too because she asks the message taker to repeat what it is that he has written down. The mother describes the soldiers that her sons are a part of as if they have one voice together, which is what I think she keeps hearing on the radio, and she is waiting for one of her sons' own unique voices to break away from the mass and reach out to her to let her know that they are alright.
