This is joy's bonfire, then, where love's strong arts
Make of so noble individual parts
One fire of four inflaming eyes, and of two loving hearts.

Couples learn to deal with their problems in order to keep their union

I am two fools, I know, for loving and saying so.

Send me nor this, nor that, to increase my store,
But swear thou think'st I love thee, and no more.

If our two loves be one, or, thou and I love so alike that none can slacken, none can die.

Only our love hath no decay;
This no tomorrow hath, nor yesterday,
Running it never runs from us away,
But truly keeps his first, last, everlasting day.
