I believe that everything happens for a reason. People change so that you can learn to let go, things go wrong so that you appreciate them when they're right,and sometimes good things fall apart so better things can fall together.
Oh man... Your tag and picture reminded me of this book I read as a kid that had a few short stories in it that was called Scary Stories 3. The story was called Running Wild(The Wolf Girl), and here's the picture lol. :)
