Fred,
I miss you. I love you. You and George used to mean the world to me; you used to be a kind of role model of what someone who everyone likes is like. You're gone, George is... quiet. What am I supposed to do now? I cry a lot, the only people who know I cry is Harry and Percy, and Percy finding out was an accident. I'm trying to be strong, mum is too but she cries a lot, remember what she was like when Percy left, well she's ten times worse than that. So me and Hermione are left to look after the house, we're quite a good team really, she's good at the magic stuff and I'm good at anything that can't be done with magic. I wish you had lived to see this side of the war, can you imagine it? You'd be able to crack jokes, we would be able to play quidditch in the garden again, and the shop would be going strong. Oh god this letter makes no sense, kind of like your death makes no sense to me.
Your baby sister
Ginny
