" Oh! my dear children, if you did but know how the heart instinctively turns from a sullen countenance — how hateful is that expression which some like to put on when they are ever so slightly offended, thinking it a point of honour not to smile or speak, but to look sulky for hours — how such a look changes the warmest love of parent, or sister, or friend, into dislike! "
