Winter- time of the year .This time, when everything around is covered with snow-white carpet of snow, good mood. But the people divided opinion about the winter. I love this time of year. And it has its reasons: It's the most wonderful time, the crunch of snow patterns on the windows, you come home from the cold and the house still warmer than in other seasons .All around covered with white carpet of snow. Looking out the window and enjoy watching the snow fall. But some people do not like the winter because it's cold, slippery, dark early, late brightens. Not only sun, everything dim, they prefer to go to a warmer climate. I do not agree with their opinion, I think it's the most wonderful time of the year .Po fact that: First, you can walk, play in the snow, skating, skiing, sledding. Second, New-Year mood New Year holidays, gifts, family gatherings. Third, the New Year's holiday. Thus, people are divided in opinion about the winter, someone loves this time of year, and some do not. But winter does not escape .and this time of year you can find the positive side, it is necessary only to want.
