A marriage makes of two fractional lives a whole;
It gives two purposeless lives a work,
And doubles the strength of each to perform it.
It gives to two questioning natures a reason for living
And something to live for.
It will give new gladness to the sunshine,
A new fragrance to the flowers, a new beauty to the earth
And a new mystery to life.
– Mark Twain
Note: Twain wrote this letter to his wife a few months before they married.
