Summer is my favorite season. 3 these months I try to relax as much as possible.

I walk a lot, swim in the Volga, read books and study English a little. I run in the heat and train.

I can’t sit still. I’ll go to my grandmother, then to my parents in Moscow, then to friends in other cities. And it fills me.

Here are my plans for 3 hot months:

1. Hand over the session
2. Relax as much as possible
3. Go to Moscow
4. Make money
5. Swap

If I follow these 5 points - this will be the most ideal summer vacation.

It is my first day in this school. This school is near my house, so I can go there without any problems. On the way to school I can meet my neighbor's dog. His name is Dodik. He is very cute. I like a canteen in this school. It is beautiful, all tables and chairs set neatly. There are many bright colours: red and light green chairs, yellow walls. Also the meal is pretty good. Classes in this school are big. Like other schools, this one also has rules like don't run, don't do anything, if the teacher didn't give you rights for doing it, but this school has one especial rule, that others don't have. It is to be happy. Initially I was worried about what will other people think, how teachers will react to my answers, but my classmates supported me and now I don't care about that, I am happy. This day was amazing, I had a lot of feelings and I like this school very very much.
