And do you know, it is a splendid thing to think that the woman you really love will never grow old to you. 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 a woman who really loves a man does not see that he grows old; he is not decrepit to her; he does not tremble; he is not old; she always sees the same gallant gentleman who won her hand and heart. I like to think of it in that way; I like to think that love is eternal. And to love in that way and then go down the hill of life together, and as you go down, hear, perhaps, the laughter of grandchildren, while the birds of joy and love sing once more in the leafless branches of the tree of age.
