Soldiers lucky enough to survive the battlefield usually get to go home. But going home isn't always all it's cracked up to be; nothing is ever the same after you've seen your comrades die. "Does it Matter?" explores this sad truth by showing us that, though the home hasn't change much, the soldier has, and so his relationship with home will never be the same.
Sure, this soldier may be home, but he's totally homeless. He doesn't feel comfortable, even when he's surrounded by friends and family, and that means he's not really and truly home.
This poem shows that war starts at home because people don't understand or care enough about the consequences of war.
