About 5,000 schoolchildren line up in the school playground and hold masks with the face of Bill Gates and the poster with his portrait to mark the 60th birthday of 'the greatest philanthropist of our time', at a private school in Chennai on October 28, 2015. Afterwards the children heard a lecture about Bill and Melinda Gates Foundation, saw a 45-minute video on Bill Gates' life history, and finally were asked to have him as a role model in lending a helping hand to the poor.
