Dear Mum and Dad:
Forty years ago you made promises to each other that you didn't know the meaning of. Marriages are made too early in a life: people make vows too young, and they move into life together with the glittery dust of youthful love in their eyes. A lot of the time, when the hardships of life together have wiped most of it away, there are plenty of excuses to forsake those promises.
You, together, have chosen to stand by your word. In spite of every little - and not so little - reason you might have found not to, you decided to keep your vows.
We, your children, have had before us an example of excellence, of perseverence, of love and determined joy, found in all the years we have watched you live, work, fight, love and endure, together.
Thank you for showing us what you have shown, for equipping us for our own marriages and the raising of our children.
We love you, as you love us and each other.
