When a man believes he may die, he wants to leave something of himself behind. Whe a woman believes her man may die, she wants that part of him desperately. The result is a great many babies born during wars. It's illogical, given the hardships that comes if the man does die, or the woman, but the human heart is seldom logical.
—Meilyn, New Spring
The teeming autumn, big with rich increase,
Bearing the wanton burden of the prime,
Like widow'd wombs after their lords' decease:
Yet this abundant issue seemed to me
But hope of orphans, and unfathered fruit;
—'William Shakespeare, "Sonnet 97"
