Dear Nancy,
Thanks for your letter. Sorry I haven't written for so long but I was busy recently studying for my exams.
So, I would to wear a black swan costume, because it represents my inner world. I would to make a costume myself, because I think, that it's conveniently and cheaper. Also because I enjoy to make something by hands. It seems to me that costume parties is cool and very interest, because they add brightness and magic. I think, that such parties have to gain popularity among youth in Kazan and in Russia in general. In what museum you will go? Do you want to go to museum? What will you do there? I'd better go now as I have got loads of homework to do.
Write back soon!
Love,
Elya
