Private
Oh, yes, you're the accomplished skater, aren't you? I must tell you that it is indirectly because of you that I finally tried out skating. You and your friend were helping Arcturus with it, weren't you? I saw his skates indoors and had to borrow them that time when the Everdale lake was frozen over. Although I did have to use a spell to keep me upright!
I'd love it if you could tell me a few useful Russian phrases! Even if I doubt I shall ever get to visit. It isn't the safest place for British purebloods in 1940.
