I want to tell you about my summer holidays. In June I stayed at home, and my parents were at work. But I was glad because I finally had time for myself. I listened to music and watched films. Then I spent two weeks in the summer camp on the seashore. Every day we enjoyed something special like games, carnivals, competitions, performances. There we swam, bathed in the sun, played volleyball on the beach, and made sculptures of sand. Then my parents were on vacation so, they took me to my parent`s place in the village. I was happy to see my grandmother and grandfather. In the evening I usually helped in the garden. Last month of the summer I was at home again. I did the usual things and prepared for school. I like my summer holidays.

Now, there are no grammar mistakes :)
