The best girl ever. She's beautiful, funny, outgoing, caring and when I'm with her, I'm the happiest and luckiest girl on Earth. Her smile is the most adorable thing in the world, and when she takes my hand I get all warm and fuzzy inside. The days when I don't hang out with her I feel so empty but when I do, the time we spend together makes up for the 14 years I've spent without her. I would do anything for this girl.
