Has Misha helped to you with home work?

Dear Mary,
I was very glad to receive your letter and thank you for it. In my letter I want to talk about my summer holidays.
This summer I spent much time with family and friends.

Summer was very hot, so I went to the river to bathe and sunbathe. Every night I went out with friends, we had fun.
July started with the events of the standard Open-2013 which I visited with friends. At this festival we have listened to good music, saw a game of beach tennis and took photos with our idols.
Later I’ve spent much time in the country, collecting summer berries.

During those 3 months I read many interesting books, found new friends, and just had a good time.
On the 1st of September I came to school and I met my classmates whom I missed a lot. I started the new school year with a good attitude and a desire to gain new knowledge.
