The Last Patronus

Dear Fred, I feel fine, I think. I sleep fine, I think. My wand is dead, I think. I'm half gone, I think. My room is half empty, I think. I eat fine, I think. I take good care of the shop, I think. There's just one thing I know for sure, Fred. My patronus is gone, and it's because of you, you great prat... haha... can't wait to see you... someday... Love, George.
