“Every one of us knows how painful it is to be called by malicious names, to have his character undermined by false insinuations, to be overreached in a bargain, to be neglected by those who rise in life, to be thrust on one side by those who have stronger wills and stouter hearts. Every one knows, also, the pleasure of receiving a kind look, a warm greeting, a hand held out to help in distress, a difficulty solved, a higher hope revealed for this world or the next. By that pain and by that pleasure let us judge what we should do to others.”
