Sometimes, indeed, in a family given to tears and caresses and easily excited feelings, a frank challenge as to reasons why is answered by a temporary storm, followed by a scene of effusion and _attendrissement_, and the black dog is not awakened, but banished, by the rousing he has got. This is a method that can be tried when you have perfect knowledge and command of your material; else it is a dangerous, and nine times out of ten would be an unsuccessful, experiment. It is nearly always unsuccessful with husbands and wives, who often sulk, but rarely for causes needing explanation. Angelina knows quite well that she danced too often the other night with that fascinating young Lovelace for whom her Henry has a special, and not quite groundless, aversion. She may put on as many airs of injured innocence as she likes, and affect to consider herself an ill-used wife suffering grievous things because of her husband's displeasure and the black dog of sulks accompanying; but she knows as well as her Henry himself where her sin lies, and to kick at the black dog would only be to set him loose upon her, and be well barked at if not worried for her pains. The wiser course would be to muzzle him by ignoring his presence; and so in almost all cases of domestic dog, however black. A sleeping dog of another kind, which it would be well if women would always leave at rest, is the potential passion of a man who is a cherished friend but an impossible lover. Certain slow-going men are able to maintain for life a strong but strictly platonic attachment for certain women. If any warmer impulse or more powerful feeling give threatening notice of arising, it is kept in due subjection and a wholesome state of coolness, perhaps by its very hopelessness even if returned, perhaps by the fear or the knowledge that it would be ill-received, and that the only passport to the pleasant friendship so delighted in is in this calm and sober platonism. This is all very well so long as the woman minds what she is about; for the passionless attachment of a man depends mainly on her desire to keep things in their present place, and on her power of holding to the line to be observed. If she oversteps this line, if she wakens up that sleeping dog of passion, it is all over with her and platonism. What was once a pleasant truth would now be a burning satire; for friendship routed by love can never take service under its old banners again.
