That was unexpect (GM)

Yesterday, I went to the store to buy something to drink. As I waited in line, there was a man in front of me and the people checking out were a mother and her teen daughter. She was hispanic, maybe 14-15 year old, shoulder-length black hair, very cute with nice eyes. As the cashier scanned their gorceries, she looked at me and smiled a very beautiful smile. I thought she was looking at someone else, so I looked behind me and saw no one and the other guy was looking at the magazines. When her mother asked her a question, she answered it, but turned her attention back to me. Turning red now, I smiled back. It was the guy's turn, so I moved up. As she was leaving, she looked back and gave me one last smile. The whole situation was completely unexpected since I don't think I'm handsome or good-looking, probably below-average at best. So, to have a young woman, let alone a young teen, smile at me and find me attractive is a very, very rare thing. Something nice to go with my soda.
