In this Wednesday, October 29, 2014 photo, Tibetan exile Tsering Topgyal sits for a self-portrait in New Delhi, India. When he was 8 years old, Topgyal's parents paid a smuggler to take him across the Himalayas, a weekslong walk over the mountains from Tibet to India. But 18 years later, he still does not know why they did it. He has not seen them since. (Photo by Tsering Topgyal/AP Photo)
