One day, is that not enough for you, one day he went dumb, one day I went blind, one day we’ll go deaf, one day we were born, one day we shall die, the same day, the same second, is that not enough for you? [Calmer.] They give birth astride of a grave, the light gleams an instant, then it’s night once more”. Which character is this quotation from?
