Who called Raju "a humble humanitarian" and why?

When Nalini and Raju's mother both move on without him, Raju simply picked up where he left off before meeting Nalini and Marco. He once again became the guide, once again the smiling face who never said, "No," or "I don't know." Raju's life remained the lie. Raju's mother moved on. Nalini moved on as well. As usual, the most important person in Raju's life was whoever Raju needed to be at the moment.
