Everybody likes holidays. New Year, Christmas, May day and others. But these holidays are for all. There is one holiday in a year that belongs only to you. It's your birthday. My birthday was on the 5 of July. In the morning my parents wished me many happy returns of the day and gave me presents. Mother gave me a jeans, father bought me a recorder. The day began wonderfully. I invited my friends to my birthday party. They came at 4 o'clock in the afternoon and brought me a lot of presents – books, sweets, toys. Mother cooked many tasty, things, among them was a beautiful birthday cake with ten candles in it. I was ten that day. We enjoyed tea with the cake and sweets and fruit. After tea we had a lot of fun. We played games, danced and sang songs. In the evening my Granny and Grandpa came. They brought me a lovely puppy as a present. It has always been my dream to have a puppy! I thanked my Grandparents and kissed them. Really, I had a wonderful birthday.
