The U to my S

Be the macaroni to my cheese.
The peanut butter to my jelly.

Be the airplane to my sky diving adventure.
The Big shot on the Stratosphere.

Be the lyrics to my song.
The notes to my minuet.

Be the polish to my nails.
The mascara to my lashes.

Be the ring on my finger.
The key to my heart.
~
I'll be by your side,
If you'll be by mine.

I'll love you till death,
If you'll be there when I die.
