Thank you for your letter. It was nice to hear you. I’m writing to tell you about Victory Day in Russia. We are celebrate this holiday on 9th of May . People usually attend Victory Parade in the morning. In the evening, families gather around a festive table to honor surviving witnesses of World War II and remember those who passed away.
