Prime Minister Narendra Modi today encouraged a #withoutfilter discussion with thousands of schoolchildren at his annual "Pariksha Pe Charcha" event to address questions on exam stress. "Let's start talking then, as they say, #WithoutFilter. We'll talk like friends, mistakes can happen. And, in my case, if I make a mistake the friends in the media will love it too..." PM Modi said, grinning at his young audience at Delhi's Talkatora stadium.
