Farewell! Forget the days of trial,
Of grudge, ill humor, misery--
Tempests of heart and floods of weeping,
And the revengeful jealousy.
Ah, but the days whereon the sun rose
To light love's wonder, and begot
In us the power of aspiration,--
bless them and forget them not!

Nikolay Alekseyevich Nekrasov
