Why is war so much like a practical joke? she thinks. Hiding behind bushes, leaping out, with not much difference between Boo! and Bang! except the blood. The loser falls over with a scream, followed with a foolish expression, mouth agape, eyes akimbo. Those old biblical kings, setting their feet on conquered necks, stringing up rival kings on trees, rejoicing in piles of heads - there was an element of childish glee in all of that.
