I met Professor Krishnan in the year 2004, in a committee meeting, of which we both were members, but soon after he became my 'mentor' in all ways. He was the person whom anyone can lean back, and was very encouraging to people like me who had been working life-long in a relatively disadvantageous place. He gave me so much 'love and affection' that he became my 'Appa' in subsequent years, a distinguished honor which only the other person on this planet shared, my father. My father passed away in March 2010, and my mother on 25 April 2014, almost a month ago when I lost my 'Appa' on 24th of May. I do not know how to cope with this sudden losses, but I seem to have lost in Prof. Krishnan a most important part of my life. However, I have promised myself, as I did to Prof. Krishnan during my very long (almost 45 min) conversation on phone with him on 17th of May, when he promised to come to Delhi and come home to bless my newly married son, that I shall try my best to live up to ideals that Prof. Krishnan has been able to inculcate in me during my ten long years of association with him. My whole family at home (personal) and in three labs (academic) would always hugely miss him. I would surely miss his warnings "shut up Vinod" during the evening sessions with Mewa and Subhedar, if that ever happens again. Appa- thank you. Finally, Mani, Prof. Bhalla and Prof. Mayor, thank you people for writing this nice piece about my 'Appa', who will always remain with us.
