I was glad to receive your letter. Sorry i haven't answered so long. i really was busy, because i am in the summer camp now. How are you?
You asked how was it going. Well, i am rather fine. I made a lot of new friends here. We are always together. We go to the river, to the forest and have much fun. In the evening we usually sing songs, play different games.

Anyway, have to go now. Write me back as soon as you can.
Love,
