As you know, when you come to a special sight where everyone is supposed to be proud of being in that particular place, you may end up finding that some people are simply wearing sunglasses to avoid being recognized, so who are those people? In fact, most of times they are important people such as a well-known celebrity worldwide who is just trying to protect herself...
So, next time you go to Paris or Milan, you would really better watch out for these persons and you may end up being surprised, I would say.
