Have you ever known someone, and I mean really KNOW them? Well I have. But I also habe come to the conclusion that we can never really know anyone, not even outselves sometimes. There are so many people, whom I'm sure you think that you have cracked down to every millimeter, but I assure you that you don't. Anyone can change, or maybe sometimes you just realize who the person really is/was. This concept can apply to freinds, family, lovers, strangers, whoever; but at the end of the day, people you think that you know can suddenly become some one else--a complete stranger.
Sometimes, when a person has come to this realisation of a certain indivisual, one has to step back and really look. LOOK at the person you thought that they were and LOOK at the person that you see now. And sometimes, when we look-- I mean really LOOK-- we often see that our tears and pain were for somone totally different a person that perhaps doesn't even exist.
Sometimes when this sort of epiphany hits you, you need to just let go, let it all go. Let go of the tears, the past, the dream, the person...
For me, it was a specific person in which I came to realize that I was after somone completely different than who I thought he was...
So, when I cry for him, I cry because I mourn the dream not the real person; the loss of the person I thought he was, not the one he is...
Always keep that in mind!
