Dear Ben,

Thank you for your recent letter. Sorry I haven't answered earlier but I was really busy with my school. I'm glad you are OK!

In your letter you asked me about summer time. I'll try to answer them. Well, I spent my last summer in the village, helping my grandmother with a garden. As for me, I really liked to take care of the garden, it is very interesting to watch the growth of vegetables! In fact, I would most like to visit France, because I dream to look at the Eiffel Tower.

Anyway, I have to go now. I promised my Mum to help her with the house work.

Write back soon!

Best wishes,

Maks (Нужно писать здесь своё имя)
