I used this sentiment inside a wedding card I made for my daughter.
THE BEAUTY OF LOVE:
The question is asked, "Is there anything more beautiful in life than a boy and a girl clasping clean hands and pure hearts in the path of marriage? Can there be anything more beautiful than young love?" And the answer is given. "Yes, there is a more beautiful thing. It is the spectacle of an old man and an old woman finishing their journey together on that path. Their hands are gnarled, but still clasped; their faces are seamed, but still radiant; their hearts are physically bowed and tired, but still strong with love and devotion for one another. Yes, there is a more beautiful thing than young love. Old love."
I added: I wish you old love.
