Cultural Shock or my experience in Santiago

Talking about cultural shock is an experience that I am constantly living today. Like I said in another post I am from the Chile's north. I was born in Iquique, and I always lived there until 2011, when I entered to the University and I Moved to Santiago.The anthropology says that a cultural shock is when two or more cultures link together, with their world's point of view, in some cases they are in a constant fight for hegemony or Resistence, Like United States and Latin America, and in some cases they take some things of each other and they build or are building a new culture, like in some borderline Cities. In my case I am alone in Santiago, so the Centralization's Weight is over me. First of all, I use some words, like "lapicero" instead of "lapiz scripto", o "Tipex" instead of "liquid" or "corrector", My friends in Santiago make jokes about that when I borrow those things. The other thing is that, the people in Santiago is very individualist, they do everything alone, in Iquique I always was with my friends, in my house or in another place. Past the time together was not a big problem like here, I guess it is for the long distances from a place to a another. My experience with cultural shock have been very difficult in some times, but I have been lucky about the people who I met, and things that I learned.

I can't understand how the people in Santiago can used the subway every day!
