My birthday is in summer. i was born on 26June. always i celebrate it with my parents or friends. Every year we go to the sea and at that time we went to the coutry to my grandparents. The first thing had attended my head before coming was that might be awful to spend birthday with sheep and cows, without friends and presents. I was mistaken. Having come i saw a big crowd of my friends, music and plenty of presents, in the evening we went for a walk. The country's air had a great smell, we was taking photos for some hours, sat near the river bank and looked at the stars. it was the best my birthday.
