Dear Masha,

I was very glad to hear from you. 

Now I want to tell you about my summer holidays. My summer holidays were very interesting. When my holidays came, I was very happy! 

I spend them in Cyprus (или любая другая страна, город, где была!) with my family. The weather was fine so we swam in the sea or we went for a walk. It was excellent! 
Sometimes we went on excursions and visited a lot of interesting places. It was great!
I met many new friends in our hotel and we had fun! Most of all I enjoyed sunbathing and swimming in the sea.

I liked my holidays very much.

Thats enough for me today. I have to go now.  

Im looking forward to hearing from you soon.

Best wishes, 

Yours Diana.
