Besides keeping her household ways thus immaculate, Mrs. Exact is on all sorts of charitable committees, does all sorts of fancy-work for fairs; and whatever she does is done perfectly. She is a most available, most helpful, most benevolent woman, and general society has reason to rejoice in her existence. But, for all this, Mrs. Exact is as intolerant as Torquemada or a locomotive-engine. She has her own track, straight and inevitable; her judgments and opinions cut through society in right lines, with all the force of her example and all the steam of her energy, turning out neither for the old nor the young, the weak nor the weary. She cannot, and she will not, conceive the possibility that there may be other sorts of natures than her own, and that other kinds of natures must have other ways of living and doing. Good and useful as she is, she is terrible as an army with banners to her poor, harassed, delicate, struggling neighbor across the way, who, in addition to an aching, confused head, an aching back, sleepless, harassed nights, and weary, sinking days, is burdened everywhere and every hour with the thought that Mrs. Exact thinks all her troubles are nothing but poor management, and that she might do just like her, if she would. With very little self-confidence or self-assertion, she is withered and paralyzed by this discouraging thought. _Is_ it, then, her fault that this never-sleeping baby cries all night, and that all her children never could and never would be brought up by those exact rules which she hears of as so efficacious in the household over the way? The thought of Mrs. Alexander Exact stands over her like a constable; the remembrance of her is grievous; the burden of her opinion is heavier than all her other burdens. Now the fact is, that Mrs. Exact comes of a long-lived, strong-backed, strong-stomached race, with "limbs of British oak and nerves of wire." The shadow of a sensation of nervous pain or uneasiness never has been known in her family for generations, and her judgments of poor little Mrs. Evans are about as intelligent as those of a good stout Shanghai hen on a humming-bird. Most useful and comfortable, these Shanghai hens,--and very ornamental, and in a small way useful, these humming-birds; but let them not regulate each other's diet, or lay down schemes for each other's housekeeping. Has not one as much right to its nature as the other? This intolerance of other people's natures is one of the greatest causes of domestic unhappiness. The perfect householders are they who make their household rule so flexible that all sorts of differing natures may find room to grow and expand and express themselves without infringing upon others.
