Conor Grennan was unwilling to be a volunteer. The 29-year-old American was not sure if he had the skills or a strong feeling for it
However, he went to work at an orphanage(孤儿院) in Nepal. His first thought was to make people impressed.
"I thought that if I volunteered just once, I could retell the story over and over," Grennan said in a Huffington Post article
However, his three-month stay in the orphanage turned into an unusual experience. It was in 2004 and Grennan had given up his job to begin a year-long around-the-world trip. His first three months were spent in Nepal.
When he arrived in the village, he knew nothing about the children or the local culture. When he opened the gate of the Little Princes Children's Home, he was faced by the excited children.
The young American ended up caring for 18 children. He later discovered that they were trafficked(被拐卖的) children. So he walked through the mountains with great difficulty to find the kids' families. "I started walking with photos of the kids," he told the Reuter's reporter. "I would show up in villages and show photographs around. I went with 24 photos, and I found 24 families. "
At the same time, he put his heart into Nepalese culture.
Grennan said, "Volunteering is the single best way to see how the rest of the world lives."
He also encouraged others to do what he had done. He believes that volunteering needs only making decisions to show up.
Grennan's fight against child-trafficking has changed him. His book, Little Prince, came out last week.
