It’s cloudy today, even at midday, it appears like dusk. In the north, people have radiators to keep warm. Which is not widely used here. During this period of time, against the coldness, I have a pair of Christmas wool socks. They are red, thick, fluffy and sort of slippery. I can easily glide on the floor with them. Today’s word is "dusk". The antonym of it is dawn.
