No mother has ever seen the girl she thought quite good enough for her boy whom she considers the model of all that is noble and manly, while that sister is rare who feels that the wife chosen by her favorite brother is what "the dear boy really needs as a life-long companion." Once in a great while, when the chosen bride by some remarkable chance happens to suit the family fancy, the whole world is informed of the fact, and the bride elect inwardly pronounces John's blood relations to be "awfully gushing" or "desperately hypocritical." The happy medium is difficult of attainment.
Of course there are some exceptions to the general rule of antagonism.

And I am glad to believe that sometimes, even when this feeling exists, husband and wife are too considerate of one another's comforts to betray any sign of discontent.

Said a woman to me: "My dear, Mrs.S.is John's mother, and it is my duty to conceal from him the fact that she is disagreeable to me.

I could be a much happier woman for never seeing my mother-in-law again, but my husband must never suspect it.

The dear fellow flatters himself that his wife and mother 'hit it off so well together.' To our credit be it said, that we have never enlightened him as to the true state of affairs." And for the sake of the man they both loved, these women refrained from outward evidence of the intense dislike each felt for the other.
The trouble begins very far back.
