You know, one thing that always confused me as a child was how people could tell what people looked like on ID cards. I understood that the picture was supposed to show the person, but since I couldn’t really see details on people’s faces I struggled to understand how they could tell if the person changed the colour of their hair or cut their hair or something of the sort. Now I understand it, but back then I just couldn’t figure out how it could possibly make sense. Good thing I never had to recognize someone by their picture.
