FINDING TRUTH WHEREVER IT MAY BE FOUND: For sweetest things turn sourest by their deeds. Lilies that fester smell worse than weeds. - Shakespeare, Sonnet 94
One more poem, this one by Walter Romig, more clever than good but worth a gander:
Nature's daughter, comely miss
Leaned her lips for me to kiss
But refused me, proven weak,
And in scorn she slapped my cheek.
Nature's daughter, not just cruel
Taunt the weakling and the fool
Prove yourself our lover when
we resist you and are men.
