Dear Rose,

Hello! Thank you for your letter. I am all right. I had wonderful summer holiday. And I want tell you about it.

My summer holiday were very interesting. I spent them in the Village where lives my grandmother. I visited her, my aunt and my two cousins. We spent time together. We gathered raspberries and mushrooms. Played interesting games. But the most I enjoyed visiting the river near the village. It was so great and amazing!

Write me back and tell me about your summer holiday.

Best wishes

Kristina
