Woody Allen.

To Love Is To Suffer

Sonja: Natasha, to love is to suffer. To avoid suffering, one must not love. But, then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love, to be happy, then, is to suffer, but suffering makes one unhappy, therefore, to be unhappy one must love, or love to suffer, or suffer from too much happiness, I hope you're getting this down.
Love and Death, (1975)

Amar es sufrir

Sonja: Natasha, amar es sufrir. Para evitar el sufrimiento, uno no debe amar. Pero entonces uno sufre por no amar. Por eso, amar es sufrir, no amar es sufrir, sufrir es sufrir. Estar feliz es amar, estar feliz, entonces, es sufrir, pero sufrir te hace infeliz, por lo tanto para ser infeliz se debe amar o amar sufrir o sufrir por demasiada felicidad. Espero que lo estés entendiendo.
Amor y muerte, (1975)
