"Don't Go Breaking My Heart!"

In other words, "You may not ever be given the chance to ever fix my heart ever again forever more!"

So, don't go breaking each other hearts which can cause much grievances for two hearts as one heart.

"Game Changer!"

Marriage is the game changer.  It will always change the game up on couples.

It says, "Can you come out to play?  Just the two of us!"

"A Sunday Kind Of Love!"

Love can be as "Easy as a Sunday Morning"!  A little history of Sunday, it is the seventh day and the last day of the week, efficiently.  Love can sometime express the same characteristic of Sunday.  Love can be pure relaxation, clear of thoughts, no need to hurry, not going anywhere, and not doing anything kind of love.  This love can put one in a comfortable bliss.  It's a Sunday kind of love! 

"Love!"

"Remembering the greatest love!"
