Fist letter (to Harry) is from "Longbottomlove", and I have premission to be stealing it :D.
Neville sat down, not knowing what he was going to say…or even why he was doing it, yet he knew that he needed to do it, needed to get the feelings off of his chest, even if only to someone who would never read it. He sat down and began to move his quill. He didn't know where the words were coming from, or where they would be going, but he knew they were his, and he knew they were true. Finally he sat back and began to read what he had written.
Harry,
I know there's a reason you've left, and that because you're on the run, you will probably never receive this, but I need to feel that someone outside these walls knows how I feel.
Hogwarts is not the same. The hallways are dead, everyone avoids eye contact, and I can't even describe how sick it is to see eleven year olds so afraid of the world. They haven't even hit puberty, yet they have seen more horrors than most 80 year olds. It is evil at its worst, taking and corrupting the innocence of children.
I am struggling to find the reasons to stay here, but I know I must. I need to be here as badly as you need to be out there. Hogwarts needs fighters, and while I'm no hero, if I need to be, I will step up to the plate for Hogwarts. I will stand for what I believe in, just like my parents.
Don't forget what you're fighting for, and that we're all together in this war, it's not just you fighting.
From,
Neville
He sucked in a breath, and folded up the letter. He stuck it under his pillow, and tried to think of what to do. He knew that Hogwarts needed someone to be there, and if it couldn't be Harry, the rightful boy-who-lived, he would try to be the one it needed. That night at the ministry in fifth year had changed him, and he hoped that it would give him the strength to carry on. He began to sit down again, and write another letter, to another pair of recipients who would never get it.
Dear Mom and Dad,
I miss you; I miss you more than you could ever know. Hogwarts is in shambles, and it is sick the evil in this world. I know that if you could, you would be here, fighting along with me.
I hope I'm making you proud. That's all I've really wanted, is to make you proud of me. I know that I could never be as brave as the two of you, but I hope that I'm brave enough to do what needs to be done.
I'm trying to find the good, but I'm not sure if there even is any anymore. People pass people in the hallways, ignoring the small horrors in everyday life. How sad it is too think that, forging lineage, or worrying if your family is alive is a "small horror", but it's what everyone faces now.
I know you guys always stood up for what you believed in, and now it's my turn. I know that you are standing with me.
Love,
Neville.
He placed this letter under his pillow with the other, and he suddenly slept much better with them there.
