Well I think it's a story of a girl wiating for a dad's return most likely form the war probably in Iraq or mabye Pakistan (the dirt represent the Deserts) mainly because alot of their songs are about those subjects and the only thing she wants is to be with her dad before losing him even if it means dying (The postcard says wish you were here but I'd rather I was there, Holding) and at the end she finnaly gets what she wants when the dirt whispered to her "child I'm comig home"
