It’s not easy being the Prime Minister of the largest democracy in the world. You have to meet numerous world leaders on a day to day basis, run the country, fight the opposition and most importantly, click shitloads of selfies.
Because #YOLO.
Irrespective of the position, at the end of the day PM Modi is after all a human. And all those foreign trips had to take a toll on him.
Which probably explains why he dozed off in the parliament. And that too, when Home Minister Rajnath Singh was discussing the Constitution right next to him!
