It is not always similarity of character that makes people friends. It quite as often makes them rivals. To have what your companion wants, and to need what he can afford you, is a better foundation for those social partnerships, often dignified with the name of friendship. The great talker wants a good listener; the sluggish or melancholic are glad of a companion who will undertake the active duty of providing conversation and amusement; he whose nature it is to lead, wants some one who will follow; and the doubting man welcomes as a strong ally, him who will decide for him. As Dogberry says, "when two men ride on a horse, one must ride behind," and the social, compliant and admiring temper of Mrs. Shortridge fitted in so well with the animated, impulsive, and vigorous spirit of Lady Mabel, that something very like friendship grew up between them. Lady Mabel's habits now underwent a change, which proved that her late mode of life, and her morning and evening _levees_ of epaulettes, had been quite as much the result of necessity as of choice. Her father's house was still much frequented by her gay and dashing comrades. But whenever there was a large company to dinner, or any other cause brought many of the gentlemen to head-quarters, she made a point of having Mrs. Shortridge at hand to countenance and sustain her; and in return she would often mount her horse early and canter into Elvas, followed only by a groom, to shut herself up with Mrs. Shortridge for a whole morning, doubtless in the enjoyment of those confidential feminine chats, for which she had longed so much. On these occasions the representatives of the ruder sex seldom gained admittance, except that L'Isle would now and then drop in for an hour, he being too great a favorite with Mrs. Shortridge to be excluded; and, for a time, he showed no disposition to abuse his special privilege.
