I've never mentioned this but, a few years ago, a friend's young son, about 12 years old -- who idolized #Nadal -- was diagnosed with cancer. He was very sick. I mentioned it to Nadal's people and, a few weeks later, I received a video of Nadal, telling the young boy to stay hopeful, that he was rooting for him and that "I hope we get to meet someday." Incredible character and generosity. (The boy is now in remission.) We will always be grateful. @RafaelNadal
