It`s snowing! It`snowing outside! I`m sitting near the window and I`m very glad because winter has come.

I like winter very much. I like white snow and white trees and white houses. There is much snow in the wood and I can ski with my sister. We like to play snowballs. It`s great fun .My friends and I make big snowmen every winter.We toboggan and sometimes play hockey with our boys.

In winter there are a lot of holidays: my birthday and my mother`s birthday, New Year`s Day and Christmas, Father`s day in February. And so many presents! And so many merry games! And we have winter holidays too! And my grandma always cook a very tasty Christmas cake.

My mum and dad, my grandma and my sister and I are very happy. I think winter is the best season.
