I was returning to my home by bus after completing the office work. It was around 6:30 to 6:45 P.M. while I was crossing the Vidyasagar Setu, also known as the Second Hooghly Bridge, is a toll bridge over the Hooghly River in West Bengal, India, linking the cities of Kolkata and Howrah. I was sitting on a window seat and enjoying this beautiful blue hour. All the fatigue was gone.
