He was wearing a grey robe, I asked him about it and he told me it was a monk's robe. Some monks only eat the food that is donated to them, so I offered to buy him dinner. He said yes, but then declined when we left the plane. I walked him to the gate and chatted with him. We sat down at the gate, and he actually said powerful wise stuff! Just like you would hope chatting with a Buddhist monk would be!
He was so nice. He invited me to visit his monastary. YAY!
