Let\'s speak about winter. Winter months are January, February and December. It\'s the coldest season. It often snows and everything is covered with snow. Streets, roofs of the houses, trees and bushes are usually white. The weather is often cloudy and the sky is grey. Days are short and nights are long, much longer than in summer. Many animals sleep in winter and birds fly to warm countries.Children have holidays and don\'t go to school. They ski, skate, make snowmen, play snowballs and hockey.
