One does not really feel much grief at other people's sorrows; one tries, and puts on a melancholy face, thinking oneself brutal for not caring more; but one cannot and it is better, for if one grieved too deeply at other people's tears, life would be unendurable; and every man has sufficient sorrows of his own without taking to heart his neighbour's.
