If there’s one person who clearly should remain on silent mode, it is Shashi Tharoor. On October 30, while delivering a talk at the D.G. Vaishnav College in Chennai, he told his audience, whose mobile phones had started ringing, “during public meetings, the organisers usually request everybody to keep their cellphones in Manmohan Singh mode. I guess they forgot to do the same here.” But when the audience burst out laughing he did some damage control.“i was just joking. Our Prime Minister is the most efficient person I have ever seen.” Too late.
