Answer:
winter mornings are cools with clear sky. It is refreshing and pleasant with low temperature.
Winter is my favourite season and so the morning is also very special to me. I dearly love to have coffee with my family members in the winter morning. We also chat with each other with a cup of tea near the fireplace. The fog which falls make the surrounding invisible to see.
On Saturday and Sunday I wake up early in the morning at 5 o' clock with my grandmother. I go for a morning walk with her. It is very refreshing to start a day with a winter morning walk The white fog widespread all around and the tiny water droplets on leaves and grass look very beautiful. I feel enthusiastic and like to do my work in a more systematic way. I sit for my study after the walk and feel that time perfect for my study. After the sunshine I play badminton with my brother and my father also. I and my brother also go for cycling together in the street.
Sitting nearby a fireplace and reading story book is my favourite time of winter. Sometimes I also do sketching near the fireplace. My favourite beverage is coffee; which I mostly like to have in winter season. Everyone like to spend their time in different way in winter season. People usually like to eat varieties of green vegetables that are available in this season. Few people also go for picnic in winter. Christmas makes this season very special. Winter morning out blooms with different flowers also.
