Fate

"Mrs. Snyder explained to me that when fate comes into play, choice sometimes goes out the window. Maybe Romeo and Juliet were fated to be together, but just for a while, and then their time passed. If they could have known that beforehand, maybe it all would have been okay. I told Mrs. Snyder that when I was grown up, I'd take fate into my own hands. I wouldn't let some guy drag me down. Mrs. Snyder said that I'd be lucky if I ever had that kind of passion with someone, and if I did, we'd be together forever. Even now, I believe that for the most part, love is about choices. It's about putting down the poison and the dagger and making your own happy ending... most of the time. And sometimes, despite all your best intentions, fate wins anyway."
