Winter has finally arrived. In a city like Kolkata, winter chills are much desired. We Kolkatans long for the brief spell of winter to re-energise ourselves. The warmth of the woollen clothes, snuggling inside the blankets and sipping on hot tea or coffee is such a great wintry feeling! It is a pity that with the worldwide changes in weather phenomena, winter is no longer the way it used to be earlier. Kolkata too experiences of late a very bleak, a very errant and a very much unpredictable winter.
