Not every person that comes into your life is meant to stay. Some people really are just lessons. They come teach you something about life or teach you something about yourself and then disappear. Its unfortunate, because sometimes you meet someone and you swear this person is meant to stay in your life forever or at least you want them to and next thing you know, they are gone. But that's just life and you have to accept that. Bridges burn.. you live and you learn..
