Darling Tater, Life is hideously unfair. Finally I'm in London and you're not! Sometimes I think the only thing that kept me going through exams was knowing I'd be home soon and I'd see you, and instead you're off in Germany flirting with blonde beermaids and I'm here alone doing nothing. Well, I know you're working hard too, but at least in my mind you're flirting (or worse) with German girls, and I need you to tell me you're not, and not just tell me, but mean it. If I can't be with you right now I at least don't want you to be with anybody else. So maybe this makes me sound like a naive little girl but, well, I sort of am a naive little girl. I only want to be with you, and I only want you to be with me, and tell me now if I'm being silly to think that could happen because then you can flirt with all the German girls and every girl you want and I'll try to stop missing you when you're away.
If that doesn't sound silly, come visit me, and soon. You could portkey in just for the evening and be back at work the very next day. I haven't been able to stop thinking of you since Slughorn's party and if I don't see you soon I think I'll explode.
