I'm crazy about this girl, my niece

Her boyfriend took this photo a couple months ago. She showed it to me Labor Day weekend and I've been bugging her ever since to get a print for me. Finally, it arrived in the mail on Saturday. Every time I look at it, I can't help but smile. I love the dappled light on her skin and the way her hair falls, but mostly it's that smile of hers that gets me. If you know her, I bet you're smiling too.
