In the tropical city of Mumbai, winter doesn't make a grand entry with gusty winds or the sun playing truant. It sneaks in stealthily when one day, you look out of the office window and realise it's inky dark already. When wrapping your favourite stole around the neck doesn't make you perspire any more. Or when you drive past the divider on your usual route only to find it transformed into a bower of petunias.
