Eu li essa história há muito tempo no meu livro de malaiala, mas acredito que ela foi traduzida de algum outro idioma (provavelmente russo?).
O enredo difícil - pelo que me lembro - é assim:
An angel visits the earth but is warned that she will lose her wings if she cries. She comes across a lot of sorrow on earth, but does not cry. But in the end, she comes across a mother who lost all her sons in war (guess that was it), and ends up crying.
