Dear Jane,
     After I left Paris I spent two days in New York. I got to Miami on Nov.13rd. The weather
is wonderful here. This morning, I met Jennifer Lopez--my favorite movie star. I asked her to
take a picture with me. You know, that was my dream. She agreed! I'm going to show you!

Dear Dad,
      I got here at last after 18 hours on a train! It's very cold here in Moscow. It's white everywhere.
This afternoon I went to have a look at the city. I got lost. I'm glad I took Russian lessons in my
university. They helped me a lot. I think I can finish my work here and go back home soon.
     I miss the warm sunshine at home. See you soon.
