Summer is a wonderful season of a whole year. Some people say that it's their favourite season. I also enjoy summer holidays. There is no school. There are long sunny days, new friends and interesting things to see and to do.
At first I've been in Pyatigorsk this summer. I was at my granny. There were many trees and mountains. The air is frish and clean. It was just fantastic!
Next I was in mathematical school also in mountains. I like it so much, because I meet there always a lot of interesting people and spend the time very well!
We all know that a great number of people go to the seaside in summer. In August I wasat the sea with my family too. 
So, at the end I can say that I have really goog rested this summer!
