When you're little, your whole world revolves around swiping sugary cereal from the pantry and your parents. So if you're a kid and one of your parents has to leave for a long period of time, specifically to live in a dangerous situation, a gray mist of uncertainty descends down on you. You can eat a slice of cake, play with your friends, watch your favorite shows, whatever it is that makes you happiest, but the ghost of something terrible is always sitting on your shoulder. Whether it's World War II or it's the war in the Gulf or you're one of the Hatfields and McCoys -- it's all the same. You can try to push the thought of the worst that could happen out of your mind, but it never leaves.
