One day — it can happen at the beginning of winter or at the end of autumn — you wake up and feel that something extraordinary has happened. Even just looking at the window, you understand that today it is lighter than usual on the street. And already looking out of the window, you will be surprised and happy: the first winter snow has fallen! The first snow means the beginning of winter. Although the snow may still melt, the air may warm up, snow is still a sign that winter has come.
