My guess and I were travelling by our tour bus, after a long trek through the mountains.This girl is smiling at us after her father over took our bus on this narrow road, after driving behind our bus for a long time, which is very a narrow and it makes it so difficult to over take another vehicle. Her smile is sarcastic and also cheerful at the same time, it like she's saying we are number one now and my father is faster than you!!!!! After driving in the front for a while they stopped and we had a chat with them. She was apparently picked up by her father after a dancing class
