Hi Stuart,

Hope you will come to Ekaterinburg this summer. As you know, I have been living here for about a year, but I have already loved this city. Ekaterinburg was founded in 1723 on the border between Europe and Asia. The location was chosen because of its rich natural resources, and the city has always been a large industrial center. Today it is also a cultural, scientific, and business center. His theaters and symphony orchestra are known in many countries of the world. We have exams now. Today I have been preparing for a math test all day. I have already solved 10 tasks. I'm glad the weather is bad. It's been raining since morning. When it's warm and sunny, I feel like going out of town and resting by the lake or playing tennis. I have been playing tennis since I was 10 years old and have already won a lot of competitions. A large sports center was constructed near our house last year, and I do not need to spend a lot of time on the road. It's great! Come over here, we’ll go around the city, go to a concert, go to the country, go for a swim in the lake, and play tennis of course.

I am look forward to hearing from you soon.

Regards,

Irina.
