We proceeded to make way across the mighty Hooghly River, a monstrous offshoot of the Ganges, where we contemplated for a moment, our thoughts seemingly caught in the roaring southward current; there we gazed, toward where the city transitions into mangrove jungle, and somewhere a bit further to the southwest where all the rivers split infinitely like capillaries, where those famous Bengal tigers trod among the sunderbans. Peering in that direction, Bajju gripped the vertical bars just above the horizontal pedestrian railing, breathing slowly and silently, knees locked, still, despite being on arguably the busiest and loudest bridge in the world.
