But he was an only child and an only son, and for a mother in such a position it is not always easy to accept that another woman will eventually enter her son's life and, if all goes according to plan--the plan being that of the other woman--take him away. This common conflict, so understandable and so poignant, is played out time and time again, and almost always with the same painful result: Mother loses. It is so, of course, if Mother is overt in her attempt to put off the almost inevitable; if she is covert, then she stands a chance, admittedly a remote one, of introducing into her son's mind a germ of doubt that the woman he has chosen might not be the right one for him. That takes skill, and boundless patience, but it is a course fraught with dangers for the relationship between mother and future daughter-in-law, let alone for that between mother and son.
