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.
