War.
War never changes. It's always the same bloody, messy affair. Some people say war is necessary, but it is necessary to watch those around you fall dead? Is it necessary to have nightmares for years? Seeing all your friends, your family, staring blankly at the sky. The smiles are gone, just agony. When did that become necessary?
War never changes. It makes women widows, men widower's, children orphans. It makes parents lose their babies. War may change the world, but it itself never changes. It just spews hatred and anger. One day you may have never thought of a person as your enemy, and the next day you are killing them before they have the chance to kill you. War is hell, and it makes you lonely.
War never changes. Never. You can't get back what you lost. You can't return to a time when everything was okay. You can't get back the days of running around carefree with your mates. You can't get back the girl you loved. All you are left with is the painful memories. The memories of your best mates rolling around in the grass, trying to get the last sweet. The memories of the sweet tender kiss you shared as the light dimmed from her eyes, staring blankly as you pulled away..
War never changes, and that's why you need to fight to end this. Why you have to keep your head up and carry on. Because one day, Harry, this war will end, and you need to be prepared to fight. You need to fight to make sure another war doesn't happen in your lifetime. I would say in our lifetime, but my time is up. I don't see a way out of this alive. Keep my boy safe, tell him I love him deeply and I wish his mother and I would be there for him. He will have you, though. He will be taken care of. I am so sorry I wasn't there for you, Harry. I wish I had been. But as I've said, war never changes. Not even the wars you fight against yourself.
I love you, cub. Be safe. Make us proud.
Remus.
