Michelle Obama rang me up at my New York hotel and we had a long chat over my concept of sex education without ‘vulgarisation’. She was quite impressed with my much-publicised views on the topic. Told me it was highly relevant to her and Barack because they had two daughters, the elder one almost ready for college. She wished for a long, personal chat with me at the White House but I had to fly back to India and if the government came to know that I had met the First Family before its scheduled meeting with Modiji in September, it could lead to protocol problems.
