My dearest Sam,
By the time you read this letter I will be on my way to a new World. I am sorry that I did not tell you of my plans, but I did not want the inevitable goodbye to weigh on your mind as our last days together passed. It was selfish, and I hope you will come to forgive me.
I am writing this because I feel I owe you, more than anyone else, an explanation. As well as more of a farewell than I will be able to give in person. Although, even in a letter there are things I can never say.
There are many reasons that I feel I must leave, and one of them is that I know how loyal you are to me Sam, and lately that hurts. As long as I am here you will always stand by my side, but I cannot allow that any longer. For I will always be stuck in the past, and if I stay you will never be able to move on.
The things we've done have has brought peace to the world, but not to me. The journey changed me Sam, and not for the better. The fact that I succumbed to the ring at Mount Doom is something that I will never be able to forget, or forgive. Even worse is how I allowed both the ring and Gollum to poison my mind against you and abandon the one person who I should never have forgotten wouldn't ever abandon me. For that I am more sorry than I can ever say.
People tell our tale as if I am the hero of the story and you my brave companion; but that is not true. You Sam, have always been the real hero. You were the one who kept me from loosing sight of myself sooner than I did. You were the one who reminded that there really is good in the world, and that no matter how small, it is worth fighting for. You carried me when I no longer had the strength to go on, and to the very end never gave up on me.
You have always been like family to me, and there is no one in the world I care more for than you. But you have a family of your own now, and I know I can have no part in it. Although it pains me, I know you will never need me as I do you. Take care of Rosie, she will make you happy in ways I never can.
I pray that one day, somehow, our paths will cross once more. Thank you, Samwise Gamgee.
Until we meet again, in this life or the next,
"When you can't run, you walk and when you can't walk, you crawl, and when you can't crawl-"
"We carry you."
