its winter time

I was reading about temperature dipping in north India, particularly in places like Mt Abu, the weather forecasters too were confirming that winter has set in. Even migrating birds were seen flocking the southern peninsula, but me was a skeptic I needed much firm indicators ….and then Amartya Sen landed. Geeeez it really is winter. What will us billion mortals be without these winter visits by saviors!!! Thank you sirji
