And then, do you know, I like to think that love is eternal; that if you really love the woman, for her sake, you will love her no matter what she may do; that if she really loves you, for your sake, the same; that love does not look at alterations, through the wrinkles of time, through the mask of years — if you really love her you will always see the face you loved and won. And I like to think of it. If a man loves a woman she does not ever grow old to him. And the woman who really loves a man does not see that he is growing older. He is not decrepit to her. He is not tremulous. He is not old. He is not bowed. She always sees the same gallant fellow that won her hand and heart. I like to think of it in that way, and as Shakespeare says: “Let Time reach with his sickle as far as ever he can; although he can reach ruddy cheeks and ripe lips, and flashing eyes, he can not quite reach love.” I like to think of it. We will go down the hill of life together, and enter the shadow one with the other, and as we go down we may hear the ripple of the laughter of our grandchildren, and the birds, and spring, and youth, and love will sing once more upon the leafless branches of the tree of age. I love to think of it in that way — absolute equals, happy, happy, and free, all our own.
