Marriage is not at all what romantic lovers imagine it to be; it is an institution founded upon an instinct; to be successful, it requires not only physical attraction, but will-power, patience, and the always difficult acceptance of "the other"; finally, if these conditions are fulfilled, a beautiful and lasting affection can be established - a unique and, to those who have never known it, incomprehensible mingling of love, friendship, sensuality, and respect, without which there is no true marriage.
