The One Thing To me there is only one thing that matters most. That one thing is something ever couple shares. The one thing that sparks their love for one another. The thing that can change the way one feels about another. The one thing that can sweep a girl off of her feet and give her butterflies. The one thing that can make you feel like your flying, but it's so passionate that you never want to come down. The one thing I crave so much every time I see a couple walking hand in hand. The one thing that ends every romance movie. The one thing that seals the dedication between a newly married couple. The one thing that matters most. A kiss.
