a mother's lullaby

it always makes for a depressing day when the time comes for the 3rd graders to read the short story "a mother's lullaby" in english class, about the atomic bomb dropped on hiroshima. if the highlighted vocabulary written at the sides of the pages such as "bomb", "lost lives", "injured", "burns", "bodies", "dead", "weak", "mommy" and "rest" aren't bad enough, the lines in the story such as "after a while the boy stopped crying and quietly died....but the little mother did not stop singing...morning came and the sun rose, but the girl never moved again."
