As an immortal, people say you have to live eternally, to watch all your friends die. Forever. Every one of them.
But I think one thing they hadn't thought of is that...you find them again. In new people. In new lives. In new bodies. They, just as energy, do not truly die. They are recycled and find new faces in which they live behind.
And you would be surprised how the faces they always find, tend to be so similar to the face you first came to know. Even when they are no longer a male, of African descent, and are now your best female Chinese friend...you'll find you'll always be looking into their new eyes, and always seeing the eyes of the friend whom you met so many generations ago.
And they will know you in their soul even when their previous bodies have departed, and with it, took their memories. The memories that you hold dear to you. Because these are your friends. And they are your life. And you love every one of them.
