Dear Michael,
Thank you for your letter. It's so great to hear from you.
In your letter you asked me how I spent the summer. I had a great summer. First I went to a youth camp, which is located near Kaluga on the shore of a picturesque lake. We sunbathed a lot and swam in the lake, played soccer, danced in the evening, etc. I have a lot of good friends.
Then, the second half of the summer I spent with my grandmother in the garden. The garden is located near a large forest. We went camping, picking mushrooms and berries and bathed in a wide river.
Nevertheless, I already want to go to school, I missed my school friends.
I'm sorry, I have to go. I'll write to you soon!
All the best,
Sergei
