Here is a poem that I think hits particularly hard.
<b>Parable on Sincerity</b>
Two men, who shared a friendship from the start,
Together fell in love with one fair lady,
And both in secret longed to win her heart.
One offered her both gifts and flattery,
And shared with her the love he bore inside.
She welcomed his affections happily.
The other, in whom jealousy fought pride,
Would give a cool and casual ‘hello’,
But never more: from shame he sought to hide.
The honest fellow soon became her beau;
The other fellow rolled his eyes and sneered,
And called the girl he loved a ditzy ho.
And so, while some make love, the others jeer,
And find in incest what they lack in cheer.
