I think that the story behing this picture might be that the girl is living in poverty. Maybe she might have been treated poorly, and she is scared of other people.

The girl’s name is Sharbat Gula and she is Afghan. The picture was taken at a refugee camp in Pakistan. This picture was taken by Steve McCurry in 1984, and her picture was on the cover of National Geographic. 17 years later, Steve McCurry went back in search for her and found her and took another similar picture of her.
