At the Trichy central bus stand we boarded No.128 towards Thuvakudi. Wife and I were on our way to the Regional Engineering College, where we had studied together in the 1990s. In a foolhardy attempt to revive the collegiate spirit and relive those days, we decided to do without the comforts of a rental car and chose to travel by public transport. The bus was already full when we boarded – all seats were taken – and soon we were rubbing shoulders (and not only shoulders) with fellow passengers, mostly working class men and women. I sensed some of them staring at me, standing incongruously amidst them in my jeans and kurta, a camera slung over my shoulder.
